My opinion without regard to price:
Paulson/TRK (tied - depends on individual chip imo)
ASM/CPC (can sometimes be better than Paulson/TRK if design is spectacular)
Bud Jones
Chipco/Game On
RT Plastic
Sun-fly/imported ceramic
Matsui/Gemaco/Abbiati
China clay (non-exhaustive sub-raking: Dunes, Great Wall, Spirit with the rest not being worth the time)
Less crappy non-Dice injection plastic (i.e., Lucky Bees)
Faux clay
Crappy non-Dice injection plastic
Super diamond
Dice
Interlocking
Pretty much this for me with the subsequent caveat of adding
BCC MGK and t-mold to top line if produced with any care and QC. Personally I'd swap the Chipco and Bud Jones ranking.
But the problem is this is just a general starting point. Just because Paulson made it doesn't immediately send it to the top of the list. There are plenty of shitty Paulson chips (*cough* $5 Aztars or Paulson mold, and some love those) and as Doc noted, condition, provenance, etc play a part.
Then consider customs. While I'd agree in general ASM/
CPC are slightly less desirable then Paulson/
BCC/
TRK, some of mine and others' customs I'd never trade for those chips because the design is too cool, personal and exceeds whatever criteria is used to define great chips. I may also add some ceramic sets like Game On Paymaster or ABC High Arctic Poker here as well.
It's a journey. It's very personal and subjective as
@links_slayer indicated.
That's why many experienced chippers express surprise occasionally when something new hits or fills a gap they've missed. For example I've never cared for
PNY's (*gasp*). But then I got to play with a mint set and they handled amazing. They would never be among my dream sets but for many they would be, at least I can understand why.
