Best case on the Google store?

I've got a 10% off code for the Google store, so I would like to get a case from there. I was originally looking at the official Google case, but I've heard that the case makes the phone really slippery and I don't want to deal with that. I've also had problems with the front part of the case not sticking with my Z fold 4. What's the best case in the Google store to avoid these problems?
