I like the fact that both have the denomination easily readable and doesn't seem to be subject to dirty stack issues.
I like the fact that both have a dedicated dealer button.
It's less relevant for a cash set, but for the tourney set, it's very nice to have added a nice bounty + a special rebuy octogon chip.
I do prefer the hybrids over plain ceramics.
For the spot patterns. I'm torn. I like the B&G style but this one looks a little bit busy to my personal taste. I also like the more simple ones of the cash set but with the smaller label zone, I'd have prefer that the spot patterns go more to the center of the chip or put the denom outside the "inlay" and increase the theme logo. It's a tie for me here.
For the theme, I do prefer the midnight casino. It's amazing how the details are nicely printed. The cash one is also nice, with the subtility of the gradient with the spot color but overall I still prefer the Mightnight Casino artwork.
In the end my vote goes to Midnight Casino.
