I can't say really whether any of them are really helping much over what you get out of the box, but PHPStorm also does way more than I really need. I used sublime for years, so having all these extra buttons and knobs and built in functionality is somewhat wasted on me. :)
editorconfig is pretty nifty, though I don't know if the phpstorm plugin for it really works all that well.. it seems to want to impose different rules despite what you put into the editorconfig... at least as far as tabs and spacing..
