I've skied the hybrid and the pure 99s and I much preferred the hybrids but then I'd rather have a damper ski than a lighter one. I've seen lots of durability issues with the pures as well so be wary of that.
It's difficult to give you any specific advise without knowing what sort of ski you like. The best thing you can do is read the reviews on blistergearreview.com and search through the TGR forms. You'll get a ton of info and different opinions on both and you can match it all up to what you like in a ski.
