Had a look at amazon and came across these brands : Otterbox, Encased, Spigen, Rhinoshield, Supcase, Dexnor, Speck,

What are everyone's recommendations ?

Previously used Encased Rebel Case for my S10.

I'm tired of "ultra thin" phone cases that claim to offer drop protection. I got the Otterbox Defender Pro for my brand new Samsung S21 Ultra on November 26th with an Otterbox case but a couple days ago, I dropped my phone from hip height onto the road and, I think, it impacted corner first and destroyed the screen. Now I'm having to pay for a new screen but before that, I want a THICK phone case, though one with extra protection for the corners of a phone will do. However, I'm finding it impossible to find any case that advertises itself as thick. The obsession is all about thin, but thin doesn't equal better or even equal protection to a proper padded phone case. So if anyone knows what is the thickest S21 Ultra compatible phone case is, please name it for me. Price doesn't matter, the pricer, presumably, the better protection it provides. Other than those made by Intrinsically Safe, which are overpriced.
