This one seems to get really good reviews on amazon! https://www.esrgear.com/products/iphone-11-metro-premium-leather-case/
Im curious about it myself but I havent got my 11 yet and the case becomes pretty costly for me in Sweden. I saw some reviews saying the feel is identical to the Apple Case they've had on other phones, which sounds promising!
agree on the Mujjo. Just bought one for my 11 Pro. I have an Apple leather case as well. Quality seems very similar. Just no aluminum buttons on the Mujjo.
