I've been switching between the Caseology Vault and the XLevel Guardian since I received my 6 pro last week.
I like both, but I may not keep either of them.
The Vault is a good case with pretty good protection, but I don't love the look of the back (prefer the look of the Parallax) and I don't like how high the sides go above the curved edges. I know it's done for protection, but I'd rather that protection come from the top and bottom. I say this knowing that I might be more careful with my phone than others because I'm a little older and my work keeps me mostly at a desk.
The XLevel case is slim and minimal and I like the way it feels and it looks. It gives very little protection but I can live with it most days and might keep it because of that and because it's inexpensive.
This leads me to the case I should be receiving today, the Rhinoshield Solidsuit.
I've had the Rhinoshield with the carbon back for more than a year on my Oneplus 8 Pro and it's been a very good case for me.
The 8 pro also has the curved edges, like the Pixel 6 pro, but the solidsuit keeps the side edges a little lower and it feels better in the hand and, to me, looks better. All the front protection comes from the upper and lower lips. The camera protection is also top notch with the solidsuit on the 1+ and drop protection is also very good.
I'm hopeful the new Rhinoshield for the 6 pro is similar and, if it is, it will probably become my daily driver case.
The only real negative of the case is that it's slippery on the sides, but that dissipates some with use and I've never dropped my phone because of it.
I'll be back with some more comments after I receive it.
