I voted empress because it has a shaped inlay and a red denom, which matches your $1 and your $25 (but not your quarter and hundred) and because I've always disliked the Casablanca inlay. But if the priority is just the clay colors, the Casablanca has the edge.
That's because we've been to Aruba many times, and I played in the Casablanca casino when it was open. My attitude is the same toward many other casino -- I like chips from ones I've played in or otherwise visited. The personal connection makes all the difference to me.
I don't expect others to share my feelings on any particular chips. I mean, I don't much care for TRKs, either, and I have zero use for chips from Ohio. but all these quirks save me a lot of money.
BTW, I didn't say what you refer to to denigrate Empress chips, but rather to reinforce how much I think they better suit the proposed lineup.
