With Lisp the paradox of choice is especially unwarranted since moving between lisps is even easier than say moving between dynamically typed scripting langauges. Learning Guile for 4 weeks and then do CL for 2 leaves you no worse than doing CL for 5. If you care about practical first and foremost, CL and Clojure both beat Guile by a landslide. Guile is marginally prettier and more fun. Clojure has perhaps the strongest FP emphasis and you may view the JVM more favourably than I do. Rich Hickeys talks are a gem whether you pick Clojure or not.
