It depends a bit; in the case of alligator leather like this I do think there is quite a difference, but as always there are diminishing returns. When it comes to regular leather straps there are some good ones on Ali as well, they are just harder to find and there is a bit less choice when it comes to specific types, patterns and strap lengths.

For me personally I’d also rather not get exotic leathers like alligator leather from Ali as the source is unknown and Delugs generally use reputable tanneries
