Never played with Corsair before, but I can recommend the one I'm using now; Roccat Kone. It's simply incredible at everything! Desktop work, gaming, browsing, supreme quality, tons of features and customization and it's even cheap to buy.
As for keyboards, I have had the same one for seven years so I know nothing about what new ones have to offer...
I think I might get a new one this fall though, a more ergonomic one, first and foremost because I write a lot at times, which is a very static form of use.
