I've had the complete opposite experience -- none of my problems with Arc are Racket-related. The things you have listed seem to fall into two categories: you prefer Common Lisp, or things that have been done in Clamp.
I think I'd be happier about switching implementations if we could update the site that most people using the language use to communicate on! The instructions still say to get a specific old version of mzscheme!
