Speaking for myself, of course. TRAMP (especially with eshell and grep), IDO, magit, effortless buffer splits, org-mode, inline execution of elisp.

I am also rather used to the command set now. To the point that it just feels natural to jump around a file with emacs. ace-jump-mode is also good. Even something as simple as subword-mode is awesome.

Really, TRAMP has been the killer feature for me lately. The way it enhances grep results is ridiculously useful.
