The "bloat" argument has been pretty weak for the last 4 or 5 years now. I can run IDEA, Eclipse and a bunch of other tools in parallel with large sizable code bases and my laptop with 8GB of RAM barely slows down. It all runs even better on beefier desktops. If it were to start slowing down I would just add some more RAM which is cheap as anything these days,

I used to adore Emacs in college, but since I've actually had to work on large projects I would never switch back to using except for when I need to bang out a python or shell script.
