I've got SKCM orange, white, and cream, and Matias clicks on hand.
No question in my opinion, the SKCMs are better feeling than the Matias. Mind you, the Matias is a great switch. Nice high actuation point, noticeable tactile feel, and a decent click. The Matias does feel a bit scratchy, and once you advance beyond the very short tactile bump, it pretty much drops off - all the force is at the top of the switch.
The orange, white, and cream all have a longer, smoother tactile bump, and consistent force throughout. My personal preference is the white. It shares a very similar tactile feel as my oranges, but it has a noticeable, louder click. I'm a bit torn on the creams. They force required through the travel is great, but they get mushy as you bottom out - the layperson might mistake them for a nice rubber dome board.
Either way, if you can source original SKCMs, that's what I'd recommend going after.
