I don't appear to be able to vote, guessing that has to do with my just showing up, but I thought I'd at least try to keep the discussion going.
The Caesar's Palace has a great brightness that the edge spots enhance. It feels really vivacious. The King is bright too, but - the edge spots *detract* from it, IMO, instead of enhancing it. Green and purple is usually a great contrast but it's not working here for me.
The Great Wall I don't so much care for the edge spots -- I usually don't care for that pattern of edge spots, I don't know why -- but I'm really into the base tone.
The Players I totally understand people saying they're basic, but basic can be clean and classic too. It's not exactly a brave design, but it's gonna look good for a long time. You gotta give points for that.
The Casa Royale just pushes my love of neon and dayglo colors. Yeah, it's off-color, and honestly in a casino chip I do consider that a big minus, but boy oh boy that's a pretty chip.
