I've now tried at least *30* different cases on my iPhone 17 Pro since last month, and the only one I'm somewhat happy with is the Spigen Rugged Armor MagFit (which also looks to be the highest-rated name-brand iPhone 17 Pro case on Amazon, with an average rating of 4.7 out of 5).
Apple's TechWoven doesn't fit right. It's too loose. The corners of my phone pop out too easily. That means the case provides zero fall protection on the corners. On the flip side, most leather case (or even "vegan leather") that I've used are too tight, with many cases bowing from the poor fitment. This includes everything from Belemay, which after testing 4 different cases of theirs makes me think they are simply a garbage company with bad manufacturing and/or zero quality control (many of their cases have magnets in random locations, making them impossible to use with any MagSafe accessory).
Everything from "Smartish" has been a joke. They call their cases stuff like "Gripzilla" or "Gripmonk", but then use the absolute smoothest material possible on the backs of their cases, which, surprise, provides NO grip.
I thought I had a winner with the Aulumu A17 Rugged case, but it has both Volume buttons and the Action Button lumped together under one big piece of plastic on the side. Just one long bar, with no way to differentiate which is which by touch since they are all flush with each other. I shouldn't have to rub my finger up and down the side of the phone, trying to figure out which button controls sound.
There seems to be a ton of cases that have clear or translucent HARD backs on them. Besides not offering any grip, these can also feel somewhat greasy to me. And just like the feeling of silicone, this is quite unpleasent.
1) Some cases have good fit. I like them to slip on easily and snap securely on all 4 corners. This ensures good drop protection.
2) Some cases have good grip. Textured backs (not textured sides) ensure they don't slide out of my hand. I don't hold my cases by the sides. I have 3 fingers on the back and a pinky underneath.
3) Some cases have good button layouts. They shouldn't stick out too far, and they shouldn't be flush with the case.
The Spigen Rugged Armor MagFit isn't perfect, but it's basically the least sucky in all of the above.
I was hoping to have the Caudabe Sheath by now, but that company seemed to have totally slept through the iPhone 17 launch. (It looks like they won't be catching up with orders until November when they should have had them all ready by September.)
