QSC or DAS PA Speakers?

Does anybody know which PA Speaker is better? I'm looking to buy a pair of 12" PA speakers and a 18" Sub.

I'm looking at DAS Vantec 12A and a DAS Action 18" Sub

Or

QSC 12.2 Speaker and a QSC 18 Sub

Does anyone know which one is better? I play techno and I need to get good quality mid's and high's from the speakers so I can get the low's from the subwoofer. Price point on both is similar under 4k with DAS being a bit for few hundreds more.

Any comment or suggestion is greatly appreciatedAttachment 28759 Attachment 28760.
