I am leaning toward the Falcon Northwest build because of the granite base. Nothing like a low center of gravity. Also, the chassis graphic is pretty awesome. 😉
I very much like the Puget Systems build as well. There's something about it that, to me, makes it look like all the parts inside that chassis are actually working together. Obviously, they're all working together, but it looks like they're all physically working together, like a robot. I'd probably take this one if I had a choice.
