Much of the functionality that I used ST for I found Vim could do naturally, with no plugins. This presentation taught me alot (https://www.youtube.com/watch?v=3TX3kV3TICU), such as basic command completion.
There is some stuff that Sublime can still do that I don't think Vim can (multi-cursor editing comes to mind, and that's still really handy when I'm making edits to HTML). Other stuff can be done by both but I happen to like ST's better (the awesome GitHub package comes to mind).
And finally, I did pay $70 for an ST license, so I imagine I'll keep using it for another few years or so. But given that I do alot of remote administration on RHEL/CentOS boxes where vim is the only thing I can safely assume to be installed, it doesn't hurt to stay fluent in vim for such a day.
