I have switched from gedit to redcar to finally Sublime text 2. And I am pretty much happy with it. At my office I use to code on textmate on OS X and I like it, but I have decided to leave it due to lack of its presence in other platforms.
I was a big fan of EmEditor on Windows - started up instantly and had great features like native CSV support and vertical highlighting.<p>I currently use TextMate out of habit, but I'm really not fond of the performance. Find in Files locks up the entire editor, and occasionally the same thing happens after committing to SVN. I've been flipping between SublimeText2 and Vico. I'd probably use Vico fulltime if it had a way to toggle between vim-mode and "always insert" mode, since I'm still a little rough when it comes to vim.
