Good place to ask this question, Scott....hopefully those with experience with both the Bubba Pucks and the Auber Instruments product will weigh in with their comments.
As the inventor of the original Bubba Pucks, I can tell you that the non-coated finish of the BPs was intentional. I subscribe to the belief that advancing spacers can be better "approved as clean" when the smoke residue can be seen rather than "hidden" ( I throw mine in the dishwasher once in awhile if I SEE any build-up). I also tested the BPs through many, many cycles, have used them for about 5 years now, and have never experienced any "crash damage on the bisquettes" (
). I originally considered several designs and materials, including rings, and rejected all in favor of the final design of the BPs due to its simple, bulletproof design and performance. I no longer have any involvement with the BPs so can't answer questions about costs, shipping, etc but I do know from experience that the Yard and Pool folks have earned a stellar reputation for service, based upon the comments on this forum.
I hope that none of these comments are taken as negative toward any other advancing spacer producer...there is none intended. Rather I'm just attempting to give your question objective feedback regarding the BPs and trust your final decision to be what's best for you and your needs... Smoke On!!
