Pros
Pro Lightweight
Sublime Text is very lightweight by default. Customization occurs on the fly thanks to Package Control.
Pro Comfortable to work with
Sublime Text has a minimap on the side that provides a top-down view of the file and keyboard shortcuts for most actions. It also supports a large number of languages and general text editing features out of the box.
Pro Multi-line select and editing
Multiple cursors and column selection allows for versatile ways of editing.ctrl + d
will select the current word and each time the command is repeated, it adds the next occurrence of the word to the selection.ctrl + click
or middle-mouse click
will place another cursor in the place that's clicked. Cursors can then be controlled together. This also permits selecting vertically.ctrl + shift + l
will place a cursor on every highlighted line.
Pro Functionality can be easily extended
Sublime Text uses TextMate's syntax declaration files to support new languages, it has all its menus and keybindings generated from JSON files, and it can be scripted to add new features using Python.
If Sublime Text doesn't support a desired language or feature, it's usually not long before someone implements it themselves - examples include the plugin package manager and the 'open in browser' command.
Pro Beginner-friendly
When you start using Sublime Text, it doesn't drown you in keyboard shortcuts or non-intuitive use-concepts. However, high-level functionality can still be easily accessed when the need for it arises.
Pro Consistent cross-platform
Sublime Text looks consistently the same across Windows, OS X, and Linux.
Pro Fully customizable
Sublime Text allows for all sorts of customization to help users change almost everything in the editor: Key Bindings, Menus, Snippets, Macros, Completions, and many more. Essentially, just about everything in Sublime Text is customizable with simple JSON files. This system gives the user flexibility as settings can be specified on a per-file type and per-project basis.
Pro Very fast
Sublime is quick to start and never slows down. The UI is always responsive and you know what is happening in the background.
Pro Has tons of plugins available
Pro Installable package manager
The package manager is a plugin and can be swapped with something else custom.
Pro IDE features without the cruft
Sublime Text, while being lighter-weight than an IDE, still supports many IDE features.
- Text from the current file is used to provide autocomplete.
- Project Support (folder browsing, scoped history, build-system declarations).
- Refactoring support is emulated through multi-select, project-wide find and replace, and regular expression search.
- Syntax-aware selection and GoTo for quickly jumping to locations in the project.
- Snippets and Macros.
- A Python console for everything else.
Pro Offers Command Palette
Command Palette allows for fuzzy searching all available settings, snippets, etc.
Pro Easy to get started
All you need to do when starting up is to install a package manager and modify user configuration.
Pro Regex commands
Regex commands help describe a certain amount of text.
Pro Customizable keymapping
From menus to commands, assign key maps to almost anything.
Pro Portable settings
Settings are modular and can be shared.
Pro Distraction free editing mode
Distraction free editing takes over your screen and removes every UI element so you can focus on code.
Pro Dynamic Build System
Choose from many build systems or craft your own.
Pro Freemium
A Sublime license can be bought but it can still be used for free. However, a pop-up appears when you save multiple times.
Pro Permits instant file switching
Open Goto Anything by pressing Ctrl or Command + P and by using fuzzy search you can look for a file in your project. The file will load even without pressing enter, so you can make sure you've found the correct file without committing.
Pro Multiple languages are supported
Pro Haxe and OpenFL integration via plugin
Both of these programming interfaces are cross-platform, open source, and easy to use.
Pro Direct server upload
Provides command line shortcut for server upload.
Pro Projects support multiple folders and git repos
Pro Allows for Vim-style editing
Vintage mode is Vim-style editing that's already built into the text editor.
Pro Support for TextMate themes and window decoration themes
Sublime Text compatibility with Textmate bundles is good, but excludes commands, which are incompatible. In general, Sublime Text syntax definitions are compatible with Textmate language files (.tmLanguage extension).
Pro Highly Theme-able
Create your own theme with online editor.
Pro Functionalities
With lot of functionalities, where other editor even not think to provide.
Pro Beautiful user interface
It's modern and beautiful, it looks clean and refined.
It's simple: the most used features (pull, push, branch, stash, commit) are accessible in one click, and are the only buttons. The other features aren't in complicated menus nor in hundreds of buttons, but rather displayed when you right-click on something.
It gives more space to the commits, i.e. the most important things. In fact, you can collapse or reduce the other menus/windows.
It displays the current path (project, branch) on an horizontal (clickable) bar at the top. It's just a matter of taste but I prefer this to the traditional "tree" view.
It has undo and redo buttons on the main window.
It supports some drag-and-drop gestures (for example: drag-and-droping the local branch to the remote one pushes it).
Pro Extremely easy to use
A lot of care has gone into trying to make GitKraken as easy and intuitive as possible and it show. Every action is quick and painless with no more user interaction than necessary. For example, switching to another branch is as easy as a double-click on the sidebar.

Pro Cross-platform
Built on top of Electron, so it runs on Linux, Mac, and Windows.
Pro Offers a simple way of undoing mistakes
GitKraken has simple undo/redo buttons that work the same way you'd expect in any other software.
Pro Some of the best integration with hosted version control services
GitKraken can be connected to Github, Gitlab, or Bitbucket accounts through OAuth. From that point onward most if not all actions that are related to these services can be done inside GitKraken. Things like: cloning or forking a repository, adding a remote, pushing to a remote repository hosted on these services can be done inside the app.
You can even manage pull requests inside GitKraken for example. All pull requests for a certain branch for example are shown on that branch's graph.
Pro Free version available
There are both pro and free versions available. The free version is pretty complete feature-wise for day-to-day operations.
Pro Under constant improvement
A quick glance at GitKraken's release notes shows how frequently it's updated. Updates are released on a 2-4 week cycle and each one brings new features and bug fixes.
Pro GitFlow support out of the box
Supports GitFlow out of the box.
Pro Has a FuzzyFinder
GitKraken has a fuzzy finder to switch between repos/files.
Pro Perfect for beginner developers
GitKraken is easy to use and is brilliant for the beginner developers.
Pro Has a dark theme
No more eyestrain staring at white screens - GitKraken has a lovely dark theme.
Pro Good keyboard shortcuts
Cons
Con Paid
Although paying for something good is far from a Con, having the competition this editor has and still have to pay for it is definitely a Con.
Con Proprietary
Sublime Text protects and copyrights its code and is thus not the freedom-ware some would like it to be.
Con Interruption while work
"Purchasing" messages box interrupts while saving file.
Con No printing of files
Sublime Texts offers no way of printing the files it edits.
Con Not a full IDE
It does not necessarily function on a project level.
Con Annoying whitespace management
All too often it does the wrong thing with indentation on otherwise blank lines.
Con Loading big files on Windows is slow
Here's a rough comparison: a 70 MB file takes about 2 seconds to load in Notepad++, whereas the same file in ST3 takes over 10 seconds to load.
Con No toolbar
Sublime Text is more focused on keyboard users, meaning it doesn't come with a tool bar. Even plugins can't toggle bookmarks using the mouse.
Con Slow development
While development has yet to stop on Sublime Text, it is significantly slower than its competitors Atom, VSCode, and others.
Con Inadequate language support
Sublime Text offers poor support for Far-East languages in Linux.
Con No RTL Support
Although it is a "text" editor, Sublime Text does not support rendering text written in Arabic or other right to left languages. The developers seems unwilling to fix this issue any time soon.
Con Often crashes due to poor quality plugins
Some plugins are quite buggy, meaning that installing many can become quite a problem regarding stability.
Con No longer free for use with private repos
You can use GitKraken for free if you're working on a public hosted repo, but you can no longer work on a private hosted one without paying.
Con Slow
Can take between 2 and 5 seconds to load a repository, if not crashing while loading
Con Must log into GitKraken servers to use the free version
All functionality is disabled unless you register for a free account and remain logged in.
There is the $99/user/yr Enterprise option. It allows you to deploy a Linux License Server in an air-gapped/offline environment.
Con Has memory-related issues
Like most Electron apps, GitKraken has some memory-related issues. For starter, it requires more memory for an action than an equivalent non-Electron application. Although this should not be a problem most of the time for people who use machines with lots of RAM (after all, RAM is pretty cheap nowadays), it can have some issues when opening large repositories and there have been cases where GitKraken failed to open very large repositories or started lagging once they were opened.

Con Not open source
It is gratis (no cost) but is not open source. The community cannot fix problems in it, audit it for security, or trust it in general.
Con Not free for commercial use
The free version of GitKraken cannot be used in commercial projects.
Con Crashes once in a while
Under specific circumstances, like resetting 5000+ changes, the GUI will crash.
Con Has annoying popup reminders that ask you to upgrade to the Pro version
Understandable, since nobody is entitled to use work done by others for free, but annoying nonetheless.
Con Amending merge output is a pro feature
In most cases of Merge Conflicts, users are stuck with auto-merge or manually resolving it by hand. This is because in the Free Tier, users can only (1) Keep File (ver 1), (2) Keep File (ver 2), (3) Auto-merge, or (4) Use External Merge Tool.
In addition, using External Merge Tools is very limited because GitKraken (all tiers) restricts External Merge Tools to only those it managed to Auto-detect. It also does not support custom arguments for the External Tools.
Modifying the merge output directly, or Selecting lines to keep/discard, is a Paid Feature.
Con Can be confusing
Con No real commitement to Linux support
Infinite loop on Fedora 28, no debug feature or stacktrace available, no clear dependencies listing.... No real support on Linux.
Con Ugly, looks like a web app
