Nomad leather case has a plastic bumper on the sides giving you greater control and less patina on the sides. The back leather is super soft and ages really well with time. But that plastic bumper makes the case add a bit of weight/size to the phone.
The Apple leather case fits like a glove and feels amazing in the hand. However, they coat their leather with wax and it does not age well often looking really bad with heavy use over time especially on the edges of the case where it contacts your hands frequently. But that glove like feel makes it great.
I use Andar/Bullstrap/BlackBrook cases and prefer them to Apple and Nomad - but that’s my personal preference.
