Ranked in these QuestionsQuestion Ranking
Pro Pre-configured with layers
Whenever you need to work on a new language that you don't have plugins for yet, you can choose to check if sublimious has a layer for that language. If it does, all you need to do is activate it and sublimious will automatically download all plugins you need for that language, add keybindings for efficient usage and set the optimal settings for these plugins.
Pro VIM centric
This plugin is perfect for VIM fanatics. It tries to add VIM keybindings to everything, even to where you didn't know it was possible like the sublime text overlay or the sidebar
Pro Ergonomic shortcuts
sublimious adds shortcuts that actually make sense. "p f" for example searches files in the current project. "g s" executes "git status" and so on, you get the idea. It even comes with a helper that shows you what shortcuts are available.
Pro Three-way diff allows easy merging of files
Pro Highlights intraline changes
Pro Built-in support for Git, Subversion and Mercurial commands
Sublimerge automatically integrates with your version control history, and lets you compare between revisions, branches, remotes, and the staging area.
Pro Can compare to clipboard contents
Con It's NOT Open Source
You can't fix or, implement nothing. And when the developer abandons the project you will be left in the lurch.
Con It's not free
Nither as free price nor as free in freedom.
Con Cannot compare text within the same file
Sublimerge can only compare entire file diffs, but not two selections within a file. Comparing within files can be useful for example, by refactoring two similar functions to use a shared function. With Sublimerge, you need to copy the sections into two new temporary tabs and compare between the two. This can be cumbersome, as if you have another untitled file, you won't be able to know which one is which.
