Everyone will have a preferce for something different. It’s a personal thing.
I prefer a NATO (not every NATO is born equal though), However almost every watch I own that came with a bracelet is fitted with one at the moment. That said they all have an adjustable clasp which makes all the difference.
Coincidentally I thought about doing a comparison on adjustable clasps this afternoon (however I was in a boring meeting and also thinking about poking my ear drums out) so have thought against it.
