Saying that "I can clearly see the difference" and calling it a "nice modern UI rendering/feel" is too vague to be useful for improving emacs or vim in any concrete direction.
Also, both Vim and Emacs feel really chunky and numb when showing completions and switching buffers. They take many hundreds of milliseconds to respond to keypresses, while Sublime responds close enough to instantly for me to not notice. It makes a big difference for something that's done hundreds of times per day.
(That said, I'm still using MacVim as my primary editor. The botched ST2->ST3 transition demonstrated above all else the danger of proprietary lock-in...)
It would help if you would send a comparison of screenshots to bug-gnu-emacs@gnu.org.
