Best Common LISP implementation?

Alright, /prog/lodytes. I've decided to learn the one true language. I was going to go with clisp, but it seems to get trolled into the ground here. Can I get a ranked list of lisp implementations? You can throw in your Scheme-ing and other lisps if you think they're better for learning. Only rule: they must use S-expressions homoiconically.

Stop spamming every Lisp thread that you see.
Someone should report you to MrVacBob, but you aren't worth anyone's time, a better solution would be to add you to the filter.
