Clarify what you specifically mean by "best". What specific features are you looking for? What style of leather case? Provide examples of what you like and what you don't like. Specify a budget. Never assume that your preferences are universal. If there was one universally best leather case then everyone that wanted a leather case would use that one case.
This is the best leather case I have ever used or been around. This is real top grain leather and it will require some break in time but it is very good. Vaja is just cheap junk in comparison. I have had a couple vaja cases for my iPhone and within 6 months they both fell part. This won't do that and is guaranteed for 100 years.
That thing looks like it weighs about as much as holding up 3 iPads and no offense but that covered bezel is awful.
I wasn't big on the covered bezel until I held it and tried it. It does add a little weight but if you want real quality leather it's going to add weight no matter what case you get. I am sure it's not for everybody but I like it and get a ton of compliments on it.
Thank you all. The end I think I'll buy the Piel Frama Case. I have read several review and are great. When you have it upload some photos. will this
