Personally, I just like the Omega clasp better though there is not much difference. I'm not trying to pass it off for being something that it's not at all. In my world, zero people care about what is on my wrist - it's just for me. I know it might be blasphemy, but I have a Grand Seiko that I use an Omega strap and deployant clasp on just because I like them better than the Grand Seiko offerings. Not that anyone ever sees it, but I like the polished look of the Omega clasp inner pieces over the kinda dull looking Uncle Seiko version (see picture). No offense to Uncle Seiko as it is a great bracelet. And, here's a pic of the SM300 - a Watchco version.
