Tbh, finding the right grip for the S21 comes down to understanding the device's center of gravity and the friction coefficient of the back panel. I've been testing a few different structural setups and I'm not 100% sure which mechanical design is the absolute 'best,' but I can share what I've seen in terms of durability and ergonomics. * Integrated loop systems: These provide better leverage for the thumb's reach across the 6.2-inch display.
* Collapsible sockets: Great for a modular setup, though the adhesive bond (PSI rating) is critical on that matte finish.
* Finger-strap mounts: Usually have better lateral stability during high-vibration activities (basically, if ur walking or running). IIRC, someone told me that the newer ultra-slim tension bands are less likely to interfere with the NFC antenna for mobile payments. Honestly, it's a bit of a trade-off between bulk and security (at least that's how I see it).

Have you thought about the brand? For Samsung Galaxy S21 different brands have advantages.
