Nothing has to be wrong with CL for me to prefer Schemes or vice-versa, and nothing has to be wrong with OCaml for me to prefer F# or vice-versa. My preference

Nothing has to be wrong with CL for me to prefer Schemes or vice-versa, and nothing has to be wrong with OCaml for me to prefer F# or vice-versa. My preference for Chicken Scheme over CL historically has been: * Chicken has always been free, with almost all of its library BSD-licensed, whereas CL used to be expensive. * Chicken has had a really good packaging story (eggs) for a long time, whereas QuickLisp is new * Chicken has always been able to produce static binaries, which, as the Go aficionados will tell you, makes deployment really awesome. If you prefer SBCL, good for you. There was a post fairly recently about how CL's library situation is becoming awesome, and I hope that continues.
