Pros
Pro Extremely customizable
Other than being able to customize the various shortcuts, iTerm2 also lets you customize the colorscheme, font, transparency, etc.
Pro Autocomplete is built-in
iTerm has autocomplete features built in. It remembers your past commands and when you are writing something on the terminal, simply pressing Control-;
it will show you a drop down menu of suggestions from which to choose.
Pro Complete out of the box
Unlike most terminal emulators, iTerm2 comes with a pretty complete set of features. It has built-in search, autocompletion, tabbed navigation, Growl support and even a built-in clipboard manager for various API keys and such.
Pro Fine tuning for fonts
It's possible to choose a font and adjust vertical and horizontal spacing.
Pro Can immediately open files inside a text editor
You can Ctrl+Click on a file path to open said file in a text editor.
Pro Supports mouse actions
Has support for mouse actions like clicking, dragging, selecting, etc.
Pro Active maintainers
Issues resolved fast by quality contributors.
Pro Works well with powerline fonts
Pro Completely free and open source
iTerm2 is completely free and open source. It's released under the GPLv2 license.
Pro Split panes
Easy to split panes to either horizontal or vertical sections. Makes it easy to observe multiple console windows.
Pro Supported by many applications as a terminal app selection
If an application has terminal integration, there is high probability it allows iTerm2 to be selected.
Pro Intuitive
Pro Cmd+Shift+I to Input all
Wanna SSH your server from multiple tabs, here you go.
Pro You only need to type in commands once
iTerm2 can store up to 4M of history of commands you already used. This, coupled with the built-in search features makes it possible to type a command only once and then search for it through the history for subsequent uses.
Pro Works perfect with Oh My Zsh
It's a perfect base to add Oh My Zsh on top of it and enjoy a lot of themes and a really pleasant look and feel.
Pro Works well with tmux
The great mouse and clipboard support that are built-in go really well with tmux.
Pro Any key can be mapped to any function
Using the Preferences Menu you can set up hotkeys to map virtually any action you can think of to a single key or a combination of them. This is extremely helpful as it allows you to use shortcuts to edit commands you are typing in the terminal and while most terminal emulators have shortcuts for this sort of thing, few of them let you define your own.
Pro GPU-rendered, blazing fast and super smooth
Many people say they use Kitty or Alacritty because they are GPU-rendered. That was true a long time ago. But iTerm2 has been GPU rendered for years now. It's so fast and smooth that you soon forget you are in a terminal.
Pro Beautiful, minimalistic and elegant UI
It's super-clean and during use it gets completely out of the way, it's a beautiful canvas for your terminal work, a pure joy that never gets old.
Pro Can be configured as a drop-down terminal
Can be configured to work as a drop down terminal like Quake.
Pro Cmd+D to split plane vertically
Very handy to use multi-tab.
Pro Smart refactorings
IDEA places an emphasis in safe refactoring, offering a variety of features to make this possible for a variety of languages.
These features include safe delete, type migration and replacing method code duplicates.
Pro Fast and smart contextual assistance
Uses a fast indexing technique to provide contextual hints (auto-completion, available object members, import suggestions).
On-the-fly code analysis to detect errors and propose refactorization.
Pro Android support, JavaEE support, etc
A very complete development environment support.
Pro Support for many languages
IntelliJ supports many languages besides Java, some of these are: golang, Scala, Clojure, Groovy, Bash, etc.
Pro Lots of plugins
Many plugins are available for almost any task a developer may need to cover. Plugins are developed by Jetbrains themselves or by 3rd parties through the SDK available for writing them.
Pro Stable and robust
IntelliJ IDEA hardly ever crashes or has any issues that plague other Java IDEs like file corruption or slowness.
Pro Intuitive and slick UI
IDEA has a clean, intuitive interface with some customization available (such as the Darcula theme).
Pro Clear and detailed documentation
The documentation is exhaustive, easy to navigate, and clearly worded.
Pro Very powerful debugger
With ability to step into a certain part of a large method invocation (Shift+F7), drop frame, executing code snippets, showing method return values, etc.
Pro Free version available
There is a free community edition (open source) and an ultimate edition, which you can compare here.
The ultimate edition is available for free for one year for students but must be registered through an .edu e-mail account.
Pro Many convenient features
These simplify the daily work, e.g. copy/cut a whole line without the need to select it.
Pro Gradle support
Pro Built-in Git support
Pro Student Benefits
Verify yourselves as a student to get more perks.
Pro Embedded database support
Creating an embedded database, running SQL script in a dedicated terminal, viewing tables and their contents, and creating a connection to an in-memory or embedded database is fully supported.
Pro Prices are not bad
I pay $24 a month and i have access to all jetbrain peoducts , so i use their many tools , i tried many others like netbeans , eclipse , etc , they re good but intelij is on the space and the sky is the limit . Been using it for 5 years and i cant tell i got frustrated using .it
Cons
Con Keycodes are not passed through following Linux standards
If you come from a Linux terminal emulator (Gnome Terminal, Konsole...) and you rely on key-combos that are widely supported in those, porting the same functionality to iTerm is possible but will require a lot of research and configuration on your part, so account for a long painful adoption period.
Con Not quite as fast as Alacritty or Kitty
Comparing these 3 terminals on the same machine/config, iTerm stands out as the slowest of the bunch. The difference may not be noticeable to all users.
Con Way too many menu items and settings
Finding the right one is like searching for a needle in a haystack.
Con Doesn't support Snow Leopard 10.6.8
Some people still use Snow Leopard or other 32-bit systems.
Con Doesn't support RTL
Con Slow startup
Startup can be slow depending on system configuration.
Con Uses a lot of RAM
Con Somewhat expensive
IntelliJ IDEA is fairly expensive, with a pricetag of $149/year.
However there is a free community edition available.
Con Built with closed source components
The version with full features is not opensource. Parts of the code are under apache licence though.
Con Cannot open multiple projects in the same window
Con Lack of plugins
IntelliJ supports a very small amount of plugins. Although these are 'quality approved', many features are missing and can't be implemented because of that.
Con Bugs are not solved as often as they should
They are more interested in adding new features or issuing new versions than solving bugs.
Con Standard hotkeys behave differently
Seems like hotkeys assignment in Idea has no logical consistency.
Like «F3» is usually next match, «Ctrl+W» - close tab, etc — they map to some different action by default.
There is a good effort in making the IDE friendly for immigrants from other products: there are options to use hotkeys from Eclipse, and even emacs. But these mappings are very incomplete. And help pages do not take this remapping into account, rather mentioning the standard hotkeys.
So, people coming from other IDEs/editors are doomed to using mouse and context menus (which are rather big and complex).
