You should play with them both, and see what you like more. I don't feel like one is objectively "better" than the other, it's mostly a matter of preference.
I personally like LFE a bit better, because of the more-direct mappings to BEAM (as you mentioned). Lisp-Flavoured-Erlang is a very honest name; it feels like you're writing Erlang, just a nice and consistent Lisp syntax.
That said, I think Clojerl is pretty neat. I tend to find Clojure's macro syntax a bit cleaner than LFE's Common-Lisp style (I still get tripped up on commas). Also, Lisp-1 semantics are a lot more reasonable...I still hate putting `funcall`s everywhere.
