My first mechanical keyboard was a Razer BlackWidow. I sold it because it was too long. These days I only like the 60% form factor, because it's symmetrical. I also play with a Nostromo on the left, so I want the mouse on the right, exactly where the keypad would be (even the tenkeyless are too long).
I didn't have a problem with the build quality. Design choices? Yes. The macro keys on the left bothered me, not because it had macro keys, but because they were on the left. For me, the furthest key in the upperleft needs to be the Esc key (I often hit the macro key instead).
I've read people around here saying how they love their Vortex Pure. I recently purchased one (typing on it right now) and it's one of the junkiest keyboards I've had the displeasure of typing on. So, I'll take people's opinions on Razer with a chunk of salt.
I recently purchased the OrbWeaver. It's build quality is excellent. I even agree with the Blue switches. But, I'm returning it, because the thumb stick is an abomination. I currently use a Nostromo and I use the dpad for modifier keys: ctrl, alt, shift. The problem with the OrbWeaver is that I can't tell which way I'm pressing. For example, if I think I'm pressing up, I might really be pressing diagonal. So, that's another design decision.
