For solid recommendations you'll probably need to give some additional details about what kind of wallet you prefer, how many cards and such you carry in it, and which pocket you carry it in.
Bifold vs trifold vs zipper vs money clip etc, front or back pocket, etc.
In general, if you're looking for leather goods, try to avoid "genuine leather" that's basically the lowest grade, and about the only nice thing that can be said about it is that it's not fake.
Basically all leather goods benefit from a bit of care now and then, like cleaning with some saddle soap and some sort of leather conditioner. Over time all leather goods will tend to develop some creases and wear. In some cases that just adds to the character, in other cases it might look kind of grungy, and that's kind of up to personal taste.
Personally I'm a back pocket wallet guy, and after using thicker leather wallets for most of my life that started to give me a little bit of back pain from sitting on it, so I switched to a thinner nylon wallet (I use a Chums surf short wall for my EDC) and that's held up probably as well as any leather wallet I've personally used (not that I bought particularly great leather wallets) and a simple metal money clip for dressier occasions
But I also don't carry very much with me. ID, a couple cards, and maybe a little bit of cash.
