The majority of the "cool" belts you'd pick up at a mall stand for example are pressed and glued so will disintegrate within a year, guaranteed. To clarify, that is anything stamped "genuine leather". Its definitely worthwhile to invest in a couple full grain (even top grain) leather belts, they will last decades. And I'm sure you can find them with the snap closure for the buckles.
Most "dress code" for work, and higher social strata virtually everywhere, demands that you match your belt and shoes (and we're talking about leather uppers here, not sneakers). Even in "casual" setting, its still advisable to more or less match IF your belt's visible.
Otherwise, you also can't go wrong ("casually") with web belts. They also hold up very well (and are far more adjustable).
