I voted italics.... Errrr wait!
I picked the Corsair because the Mx Red switches are a great dual purpose typing and gaming switch. The blacks are great for gaming, but typing can be a bit more of a pain if you are a touch typer due to the slightly higher resistance and those "outlying" keys can cause a bit more strain if typing over time.
I love mechanical. I have the BF3 edition and while good, the bottoming out noise is a bit higher. Right now I'm using a white alps/fukkas switch based keyboard from SolidTek (KB-660U) that I love. These are similar, though slightly quieter than the Cherry MX blues with a slightly less sharp noise though similar feel. No back-light but so far I'm liking this a bit more.
