I also like that it’s easier to remember most Sublime Text 2 commands – the Command Palette (⇧⌘P) lets you fuzzy search all commands. So you can search for “syntru” and find the option “Set Syntax: Ruby” instead of having to remember Vim’s “:setf ruby”.
Finally, I use Expand Selection to Word (⌘D) to quickly select multiple instances of a variable whose name I want to change – it’s slightly more convenient than it would be in Vim.
On the other hand, I miss Vim’s editing model. It’s a lot more cumbersome to edit line-wise or move the cursor with Sublime Text’s keyboard shortcuts. And Sublime Text’s “Vintage” Vim emulation mode is a poor substitute. As another commenter said, Vintage is in the uncanny valley. Every now and then you run into a Vim command that just doesn’t work and it breaks your flow. For example, Escape is overloaded as both “go from Insert mode to Normal mode” and “collapse multiple carets into one”, and I never remember which it will do when I have a multiple selection in Insert mode.
