Chicken has free call/cc due to the Cheney on the MTA memory management. This is very rare. Most often it doesn't matter much, since call/cc is rare enougn. I would still prefer delimited continuations since they are easier to reason about.
Most often you pick one implementation and stick with it. Scheme is not like CL where you can run the same program on many different implementations without much fuss.
Chicken is a very nice implementation with the most friendly IRC channel on freenode.
