I have a Cherry G80-3000 with POM keycaps. They have a nice deep sound, and their surface texture is just as durable as PBT, but they are slightly slick and have a slight shine to them. I've never had issues with my fingers sliding off of them. Cherry only makes theirs in black with foamed legends, which wear and get dark over time. I don't have any experience with the jelly ones, which seem to be the only way to get POM keycaps in any kind of colors. I'd love to see a set with better legends, because other than that, they're great keycaps.
