I also just started my chipping journey, but here are my thoughts: few months ago I also just wanted to upgrade my ABS Chip set and ordered samples of a few other ABS chips, China Clays and Ceramics. But as always, I wanted the real thing (real casino chips aka Paulsons or atleast real compression molded clay chips).
Now I ended up having a nice ceramic tournament set and a used cash set of Paulsons (nearly completed).
Paulsons have beautiful colors, the best sound, great shuffling and stacking ability and for me most prominent: a great inlay. It's not a sticker, and you tell the difference instantly. It just feels like much higher quality.
I never had CPCs, so can't talk about them, but if you want to go cheaper, I'd say CC are getting 'relatively' (with still a large gap) close to Paulsons regarding sound, feel and shuffling ability. Ceramics can be nice aswell, but also have their flaws.
However, many of my casual friends might not even notice and for them the 'chip upgrade' is not really a big deal. Also realistically speaking, Paulsons are definitly more expensive >$1.5/chip. But you get what you pay for.
