FWIW.....
I have owned or extensively used the original Chipco ceramics (both casino and fantasy sets), custom and stock chips produced by the original Nevada Jack's company, Palm Gaming ceramics on two different blanks, Game-On ceramics, several different variations of Sun-Fly ceramic products (including hybrids and molded ceramics), original BRPro Poker ceramics, ABC/BRPro ceramics on two different blanks, the recent Chinese-produced molded ceramics, and a couple of older really crappy low-end ceramics (Nile Club, Scrolls).
Excluding those last two, there is really no significant difference in chip quality or durability between the best-of-the-bunch and the worst-of-the-bunch -- although some do feature better print quality. Personal opinion about feel, sound, and edge treatment will vary, as those items are more subjective and difficult to measure or quantify.
It mostly all boils down to the finer details, aspects of convenience, timing, and service, and what you are willing to pay.
Some like original Chipcos. I don't; I could never get past the required white outer ring, some colors were notorious for print bleed, and I felt that for the high price they charged, there were other more attractive options.
Some like Nevada Jack's (original and ABC-produced versions). I don't; I dislike the rough finish and resulting loss of print quality, and personally find the design unappealing.
Palm Gaming (PGI) was a hit/miss crap-shoot on print quality but if done properly, they were excellent ccustom ceramics and very reasonably priced.
Game-On (GOCC) offered a great custom product at a premium price, but customer service and communication has vanished to the point that the company is no longer a viable or reliable resource.
ABC/BRPro offers a solid product for a competitive price for stock items, along with quick turn-around and great customer service, although customs/features can quickly escalate the cost.
Some like Sun-Fly ceramics. In general I don't; I dislike their signature glossy edge treatment, and I think other options offer better ceramic print quality. However their ceramic hybrid and molded ceramic products offer products not available elsewhere (until recently). I like the 43mm hybrids with small recess (although disliking the glossy label and glossy edges), and like their molded ceramics better than their standard blank products.
The molded ceramics from China have squarish and matte-finish edges, excellent color print quality, and prices that are one-half to one-third of other current custom ceramic options. Downsides are communication challenges, long start-to-finish times (for large orders), and either expensive or slow delivery options.
I think we are lucky to have three viable options for custom ceramics (and wish it were still four). Bottom line is buy what you like best for the reasons you find most appealing, and let others do the same without unnecessary judgment.
