I made a similar switch to SublimeText, at least for programming tasks (non-programming tasks I still use vim since it works with just a terminal). Vintageous has a much better vim emulation than Vintage (the default vim plugin to ST), and ST has lots of interesting plugins. And I can use both modal and non-modal shortcuts (I use, for example, Ctrl+S to save rather than Ex-mode's :w since I find it less disruptive for my workflow).
