I really like them! I mostly used Apple Silicone cases throughout the past year with the 12 Pro Max. I'm a bit of a case fanatic and while I bought leather it never felt 'nice' plus the natural aging (not patina) looked really bad for people and I rarely used the ones I bought... also as leather is absorbant it never I was more fearful it would pick up grease.
I also have a preference for 'proper' magsafe over 'magsafe compaitble' the otterbox magsafe were 'official' but I didn't feel the magnets were right and I still haven't established if they have the orientation magnet for things like the wallet.
So after buying near enough 15 cases over the past year I always came back to Apple Silicone with the seasonal colours giving me a change.
Lighter colours are better for resisting fingerprints and I've never found lint to be a problem, it may pick up a bit when you first get one, but it's never been an issue after a day or two. Unless you have a constant stream of new clothes I'm not sure how anyone generates an amount of lint that is problematic on a daily basis!
Oh, and I think grippyness is ideal, could be problematic if you like skinny jeans but in and out of pockets I've been happy, I do like the feel in-hand.
