Hi, first time poster here.
I've tried the BWU, but haven't had the chance to get my hands on a DAS yet. But comparing the BWU against the few keyboards that I have tried (filco browns, blues, blacks, ducky browns, and cherry reds), I find the feel of the BWU (supposedly Cherry MX Blues) to be inferior to the blues of the Filco. Unless you want the macro functions of such gaming keyboards, I think you would be would be better off getting the DAS if you're limited to the two choices. I find typing on the BWU to be quite disappointing when compared against the other keyboard I've tried.
Curious: Aren't Cherry Keyboards made in Germany? I've managed to get one of those just a few days ago, and I enjoy it alot. Build seems a little flimsy, but the feel of the switches are superb.
