I've tried 5 cases.
1) Apple fine Woven.... utter garbage for $60
2) Mujjo Leather - feels like crap, fit is bad and it smells of chemicals
3) Lonli Classic - Feels like plastic
4) Lonli Edition - now this one surprised me given the classic was awful. It claims to be full grain leather and feels very nice. It DOES have an actual button for the action button despite the pictures on amazon showing a cutout. The buttons look a bit crooked when on the phone though and the area around the volume buttons pushed away from the phone a bit. Could probably live with that especially given the price. However, reviews for the 14 pro edition case had a lot of people showing theirs peeling....so while it might feel like good leather, I'm not sure it is. The lip protecting the cameras is just barely high enough to clear the lenses so not great there.
5) Andar Aspen - I keep coming back to this case over the Lonli Edition. The leather just seems to be actual full grain. I wish it had a button instead of a cutout for the action button (I'm sure they will release one soon). I would prefer matching color buttons and camera surround to black, but not a deal breaker.
I'll probably keep the Lonli Edition and Andar Aspen...the others are going back for sure. If you order the Lonli, be sure it's the Edition...the Classic is trash. Crazy since it's the same company, same price.
As a side note, titanium in black at least sucks to clean. at least with mirrored stainless fingerprints wipe right off. This matte titanium stains and it takes moisture and microfiber to buff it off. That paired with the aluminum internal frame and the results of the bend and drop tests and Apple has gone backwards in durability. Reminds me of the 6 Plus bendgate issues. Makes me really paranoid swapping cases. They should have gone with brushed stainless or at least kept the internal frame steel. It ain't THAT much lighter. Maybe those with the natural titanium are faring better.
Some comparison pics.
