Its a ton of little things that add up, mostly speed though. For example, a project-wide search in Sublime doesn't block the UI thread, Cmd + T works like a dream (much better than TM), etc.

The list goes on and on, its just much more well executed than TM.

Thanks for the reply. I can agree on the cmd-t thing. I'm not tied to TM but I do like the details it implements and it's usually not slow for me (granted, I can see the problem for some cases). I have been watching Vico pretty closely though and it's top of the candidates for me right now.

Sublime 2 looks nice but I couldn't get passed all the quirky settings I had to go through (in different places too) to get anything close to what I wanted. I'm still looking for more good reasons to invest the time to set it up is all.
