Honestly, you're asking the wrong guy, I'm the guy who has not met/bought a case that he dislikes.
As for worries about the rubberized surface melting on you, I don't think that there's any cause for concern, it's quite similar surface texture-wise when compared to my UAG case on my S24U...the ring stand on the UAG is kinda hard to pull out, much easier on the Supcase Trifold case.
Its thickness relative to the UAG S24U case...
The privacy screen cover when viewed directly...
When viewed at an angle, definitely not as good as real privacy screen like on the S26U, but hey, it comes with the case as a freebie, so can't complain hor....
Overall, in terms of build, quality and craftmanship, hands down better than any and all the generic China made cases. It does add a little more buld compared to the China ones, but it feels more solid, like it'd survive a drop much better than the other generic ones.
