I also got a belt with an A buckle and I like this A buckle better. The main reason I like the A buckle better is that F style buckle has two metal pieces that make a bit of a clanking noise when the touch each other (this happens only when you adjust the belt). It does not happen when you wear it but if you need to take a bathroom break... My husband wears this belt when we are doing wild life photography so even a tiny noise could spook the animals. If the noise is important to you the A buckle is one piece and makes no noise.
You can find it on Amazon by following this link.
