If you are happy with the IDEs then just use them. Having learned both vim and emacs over the past few years. I learned emacs so that I could use slime with lisp. Vim so that I could edit stuff on any server. Emacs has a big learning curve, vim is a bit easier to get into. If you use a mac you can try textmate, I've heard good things about it. On the vim side macvim, gvim are pretty good.
