That depends on what you want out of the case, wallet, flip cover, pouch, plastic, leather, metal/wood, etc. There are some really great cases, personally I want a Live Edge from Carved
https://www.carved.com/shop/iphone-x/solid-wood-cases/ but they are nearly impossible to get, you have to get on their instagram alert and watch twitter, etc and frankly I work for a living and I am in client meetings so I simply can't wait by my phone for a case to come up. Too bad they are my favorite wood case.
