Most of the decision to buy the Black Widow was due to the fact that it was in stock at the local retailer, and there were no Corsairs (at all) D: I'm super impatient, so I hate having things shipped.
The Black Widow does what I need it to do, and it's still a major upgrade over my last keyboard, so I'm pretty satisfied with it right now. I'll look more into Corsair in the future though
