I've been using the Massdrop Granites for a few weeks, and they don't feel significantly different to any other Signature Plastics DSA sets that I've used in terms of texture, thickness, or feel. The legends seem consistently printed, although I can see why some people might have alignment issues. The tilde (~#) key seems odd compared to the others, for instance. I'm not convinced there aren't quality control issues--I've heard about broken stems too, and my particular set has some odd shiny bits of plastic on at least two keys.
For those saying they prefer GMK or JTK, then I definitely see what you mean. I currently have Granite DSA at work and EnjoyPBT at home (from the recent EnjoyPBT Dyesub/Blank Keysets & CMYRGB Mods group buy). I much prefer the feel of the EnjoyPBT caps, and the profile too. Although I like the way DSA looks, the thicker EnjoyPBT and profile suits me more. And it feels great.
