As someone who uses Eclipse pretty regularly, what don't you like about it? I'd never really used big IDEs before I got into Java either, so I'm curious.
Well, for someone that uses VIM/Emacs heavily, Eclipse might be fine as an IDE, but I don't like to use it as an editor. When I'm using eclipse to edit code, I feel like I'm using microsoft word -- user friendly, but not "coder" friendly.
Also, try using eclipse on very large projects -- it gets very slow. Sometimes I'm not sure if eclipse is hung, or if it's still stuck compiling something or fetching something in maven.
I really would recommend sticking with it for a while and then moving on to vim once you've got some experience in the process.
