I use clojure over common lisp because I find the ecosystem (libraries) a bit more approachable (feels like there is more web oriented stuff in clojure, plus gui support with javafx.) That said, the actual experience of working in common lisp is better (bit better repl/recompilation, conditions, native compilation.) Personally, I don't find scheme as practical for writing programs as either of these two options (too fragmented and/or niche.)
