I’m currently using the Massdrop CTRL keyboard with Halo True switches. I installed the Massdrop x MiTo XDA Canvas Custom keycap set with the wolfgang alphas. The keyboard is great and once you figure out how to program the firmware and flash it, there are a bunch of options and RGB LED settings you can use. I don’t usually care about the LED thing, but I did put in a couple of patterns that pulse red like KITT from Knightrider. I don’t use double-shot keycaps that would allow the back-light to shine through, so I don’t usually bother with that.
