What kind of leather actually lasts the longest in belts?

I’ve been overthinking belts lately, especially when it comes to durability. Not even in a fashion sense, just something that actually lasts with regular use. I kept seeing different terms thrown around full grain, top grain, genuine leather and at first I thought they were all basically the same. Turns out they’re not. From what I’ve read, full-grain seems to be the one people trust most for long-term use, while “genuine leather” is kind of hit or miss depending on how it’s made.

What confused me more is that a lot of belts look solid online, but you can’t really tell what you’re getting just from photos. Some are thick and sturdy, others feel like layered material that might crack after a while. Even browsing through places like Alibaba, you’ll see similar-looking belts with completely different descriptions in terms of leather quality and thickness.

So now I’m wondering when people want a belt that actually holds up over time, what kind of leather do they usually go for? Is full grain really that much better in everyday use, or is it one of those things that only matters if you’re paying close attention?
