I’d refrain from commenting on stuff you haven’t used.
Bullstrap is nothing like Apple’s leather. Apple cases look nice and have great buttons but whatever they coated their leather with feels nasty after a few weeks. Bullstrap cases are vastly superior.
Regarding Nomad, this description couldn’t be further from the truth. First of all, it ain’t rubber and it feels nothing like it. It’s TPU with a frosted finish that feels great. Sure, you could be cynical and say the leather is “slapped on the back”, but in my opinion the transition between the two materials looks and feels seamless.
It really depends on what you want in a leather case. If you want full-on leather I recommend Bullstrap or Ryan London. If you want something a little more durable/rugged, go with Nomad.
I've been using a Nomad folio case on my iPad for more than a year, and on my XS for about four months. The iPhone case cost a total of $12 shipped, as an outlet closeout with a sale code applied on top.
My biggest beef with the iPhone case is that Nomad omitted the sleep/wake magnets, not helped by the stiff action of the side button needed to put it to sleep, but otherwise, it has the same qualities of its big brother, which I've been quite pleased with. Not sure if that's something they rectified with the newer cases, but in any case, so to speak, it was $12, so much easier to digest.
The Horween leather has a fantastic aroma, which fades, sadly, and patinas just like Nomad clearly promotes. That's why this thread exists, no? Contrary to some conceptions, leather is not a homogeneous material. Different cuts, different splits, different hide species, and different tanning methods. Personally, I'm not a big fan of leather that's made to look perfect, and wear like iron; might as well be vinyl in that case, marketed with some BS made-up term like "vegan leather."
Otherwise, the moldings are clean, and well done, particularly on the iPad case where the edges meet the screen, with a neat and refined design, like it was a native part of the device. The TPU is stiff enough to not warp, peel or fold over in response to pressure, like a cheap case might.
I can understand the subjective dislike for cases that have exposed non-leather edges, but the fact of the matter is that almost all cases have to have some sort of plastic shell backbone to give the case form, and provide some protective properties. Basically, every case uses a leather veneer whether it covers every bit of surface or not.
In that respect, the precision and fit/finish of the seams where the leather edges meet TPU is also top notch, and has proven to be durable thus far. On a cheap case, such vulnerable areas would be first to show signs of wear, or detachment, particularly the parts surrounding the outer edges of the camera opening, where the leather is very narrow, and has little surface area, making it more delicate.
I recall there is a company that did/does make a phone case that has no inner shell, and is basically two pieces of stiff leather roughly molded into the desired shape, but I don't recall its maker (who changed names), only that looked crude, and ill-fitting, like a beginner project of some kind. I think it also had awfully applied, mismatched edge coatings as well.
