The gap is in quantity, not quality. You'll notice Xbox exclusives tend to sell more.
Also bear in mind, the PS3 had almost nothing to play, other than multi-platform games, for almost the first 2 years. MS focussed on first party dev, and exclusivity deals - and most of it gained nothing. They started the generation with fantastic variety, and most games not targetting their core demo didn't take.
Likewise this gen, they're starting strong, with the better lineup (up to this point), but Sony has more first party devs for games later on in the pipeline.
