I literally own about 22 sets. Dyna Palladium and Tungsten, Centennials, Arcos II, Duramith, Elephant, Vigma, and quite a few other brands. All play about the same. Certainly all of the first 5 are fantastic and consistent. Honestly, I would put the Vigma brands in top tier as well.
The ONLY difference I see in any of my sets is how long they stay clean. All of my non top tier sets get dirty much more quickly. The Dynaspheres and Arcos II sets seem the best to me for longevity of cleanliness thus I suppose best finish. Centennials and Duramith I see NO difference between but they are not as good as the top two. I previously had a Centennial set that was over 20 years old and still looked good as new, but they did have to be cleaned a lot more often. My new set seems to be a significant improvement.
Either way, buy yourself a nice "Clean Gleem" 8 ball cleaner (or 16 ball cleaner. I have the 16 and love it) and toss them in for a few minutes and they are all going to be shiny, consistent and similar.
I change my set out every week and clean the outgoing set for 5 min in the machine and I never have anything but a great playing set on the table that keeps the table interesting.
