FWIW -- I have 3 sets of CC chips -- the CPS, the 8Va, and the Majestics. A couple of years ago I did some testing with those chips, ceramics (from PGI), and Paulsons.
The CPS were the PGI group buy chips and the Majestics were the Apache group buy chips. The 8Va's I got from PGI with custom labels and have been around a long time.
For the testing I used 20 chips in a stack. I tested 5 stacks at a time. The test consisted of stacking them on my cash box 1.75" from the edge (I called it the tip test). Since the lid is hinged, I could uniformly raise the lid so each stack was at the same angle. I covered the box with a non-slick material to see which chip stacks toppled first through last. For comparison, I'll give the results for these 5.
This is the order from most slick to least slick:
CPS (3) 1, 1, 1
8Va (7) 2, 3, 2
Ceramics (10) 4, 2, 4
Majestics (10) 3, 4, 3
Paulson’s (15) 5, 5, 5
I tested 3 times and in each test, 1 indicates which stack toppled first and 5 was last.
Based on this, the Majestic mold is the least click of the CC chips I have. What this test does not show is how much better the Paulson's were! They were just the last to fall, they were the last to fall by quite a bit.
I primarily use the CPS and Majestics. The Majestics are not as slick in my experience. Most of my players love the chips because they are comparing them to slugged chips or unslugged plastic chips. In my experience, the CC chips are must less slick than plastics.
I got rid of the chalky appearance in both sets by just putting them in play and not oiling them. A night or two and the colors brighten considerably.
