No Rant:

I guess I will start a religous discussion with it but I want your opinion on what tool I should learn.
Vim or Emacs (or stay with my IDE)?

For all of my programmer life I used IDEs... From Eclipse over CodeBlocks over VS to IntelliJ.
But now I realized that I want to be one of the cool kids. And using plain IntelliJ is uncool. No matter how much I love this tool.

So now I want to invest some time into learning. I never managed to do much in Vim since all code-completions sucked ass, feedback on syntax errors was bad and I never saw how I could be any faster with that shit compared to what IntelliJ does for me.
Will Emacs solve all those problems? Will Emacs make me code 1000 times faster and make having a mouse useless?
Or am I just too dumb for Vim? Can Vim itself do what my IDE does for me? Will it make me look as cool as I want to be?
Or should I stick to IntelliJ and just install Vim bindings?

What is your opinion on Vim vs Emacs vs any IDE?
