i agree, listening is the only way to really make an educated choice. both kenwood and pioneer have very similar archtictures, so i think you'll end up choosing by price and features. i've installed both, and i'm sure you'll be happy either way.
keep in mind line-outputs, though. just in case you want to add a sub (or subs) later. the more line-outs, the better, IMO.
good luck!
