I have the TKL with MX clears and the blue (thicker) o-ring set. I didn't used to like the feel of mechanicals before I tried a co-worker who had put o-rings on his. It makes a big difference in the feel and travel. Much more "laptop-y" but still tactile. I still wish they had a bit less travel, and I wish the keys had much smaller gaps between them (and less depth to drop stuff into, Apple-style), but this is probably the best thing out there right now IMO. I really wish Apple made a backlit black-key keyboard, basically the 2011 MBP (newer rMBPs and all the airs have shorter travel) but external. I have the Apple desktop keyboards and the keys on them feel too thin / hollow / cheap and aren't backlit. The travel also feels different than MacBooks in that it feels less solid, as if the caps wiggle around more or something. Super nit-picky but that's what I like!
