Having used UAG Monarch for the Fold, Spigen Slim Armor Pro for my Fold 2, I kinda like thicker cases for better protection. No point in getting a cool looking and stylish slim case that doesn't offer much in the way of good protection. Without even getting the phone yet, I've already gotten three cases ;
1. Spigen Tough Armor
2. VRS Design Active (Quickstand)
3. Araree Nukin 360 (transparent case with hinge protection)
Also bought a Spigen Rugged Armor case for the Buds 2 I'd also included with the Flip 3 pre-order. I'm more into function over form....
