Plug: I maintain a fork of termite which doesn't require Daniel's patched VTE3 fork; and guts most of the exotic vimmy features.
I really like VTE's behaviour; even if the performance is a bit worse than XTerm (though worlds ahead of what I've seen on OSX with iTerm2 and Terminal.app). I rely on using iBus input methods in the terminal on a daily basis, and VTE handles this wonderfully.
