I love my DAS. Ultimate Clicky version. I do wish I went for the Brown switches though as the click loses its nostalgic factor over time. Very high-quality feeling. Never was a fan of Razor products because their mouse's build quality was sub-par when I compared them to Logitech. Thin cords and general problems all around. I believe I didn't go for the Black Widow due to it having quality control issues with quite a few people; I'm not sure what it was though. DAS is apparently well-regarded by many typists. No lighting though if you are into that.
