Kakoune is always super tempting to me but the plugin thing is a deal breaker for me. Not for IDE-like features but because limiting myself to vanilla vim motions feels like using a bad vim plugin by now.
At least surround.vim, targets.vim and a couple custom text objects.
Caveats: if you depend on plugins to give you an IDE-like experience in Vim, kak is not for you. Your vim plugins won't work. If you use Windows but don't want to use Cygwin, kak is not for you.
