Your favourite lisp(s) + emacs + Slime (+ paredit) constitute a fabulous development environment that is widely used, and therefore widely supported, on #lisp. Eschewing this environment for something else will make it far harder for people to understand your problems and (if you ask nicely, and intelligently) help you with them.
(I also find it telling that when the smart folks who started developing lisp had the time and energy to build editors they built emacsen.)
However, if you really can’t stand emacs (perhaps because of a childhood incident with Richard Stallman, a wasp’s nest and a jar of manuka honey), you could use plain Vi (and give up the wonders of Swank) or Cusp, if you’re an Eclipse fan.
But don’t come running to us when something goes wrong.
