Well, both of them have strengths and weaknesses unique to their character. I personally find Dean Winchester to be better, but let's first establish the aspects of it... First, Sam's willpower is stronger, hinted many times throughout the show, but Dean's a better hunter. See, Sam was able to intrinsically overpower Lucifer, which in itself is impossible, and also perceived a flashback of the Cage, but was still able to function, instead of instantly become a wreak, like Cas thought he would, which says Sam's has a stronger inner core than Dean. On the contrary, Dean's physically stronger and a better hunter.
