I personally use the clear silicone ones bought a case in the past for £70 dropped my s9 smashed so just go with the the clear ones as I dont think any case will protect a phone from breaking, but I personally find the clear silicone ones the most comfortable.
I'm using a spigan and can honestly say its a very good case. I used to use beetle but I've recently starting using this and its a great case. I have the s20 ultra btw so I like my phone protected.
I always get the official ClearView flip case (S9+, S10+ and S20+5G) and have never had any issues. Expensive, yes but I think they are worth the money over time. Hell, if you were after S10+ I'd have offered to send you the one I no longer use
