speaker comparison

Alright simple question but I know I'm goin to get 5000 different answers.  I'm down to a few brands and I'm having trouble deciding.  First let me set the basics down.  The system will be a custom, SEALED, fiberglass enclosure.  I will have them in a trunk.  Probably will be running two 10" subs.  The amp will be some (MTX or maybe Polk) and will be pushing 600ish watts x 1 at 2 ohms.  I'm trying to decide between Kicker's 10" Comp VR's, Infinity 10" Perfect, or JL 10W3v2.  Take the same system (tuned to each sub of course) and just change the subs.  Which will have an overall better system (spl and sql combine).  I know that there is no right or wrong answer to this, as I am looking for other's thoughts and opinions.  Thanks ahead for all the input.

If it was me I'd go with the Perfect.  I've heard both the perfect and the jl.  I liked the sound of the perfect better.  I don't care about SPL and have no opinion on that.  I have not heard good things about kicker sound quality lately.  They're probably plently loud, but either the perfects or the jl are probably better for SQ.

Yeah I've hard the kicker's but they were in a professional sound room.  (aka they were in perfect position for perfect sound)  but then I've heard both others and they sounded good also.  But not sure, just wanted an outside opinion.  Keep them comming.
