It would be a listener preference. You'll need to decide that as there is no clear cut favorite. I've heard them both and they both sound good. i wasn't looking to purchase though so I didn't compare that closely. I already have a better set of tower speakers, they cost more though.
The Infinity has a higher sensitivity and will play louder at the same volume level than the Pioneer speakers. Playing louder does not make it a better speaker though. The sound quality preference is for you to decide. Each person hears different things so this is a subjective decision.
