They are in every way the most base method of displaying wealth.
The leather used is amazing, but the leather costs about $150. The Golden H? $550, just so that people know you're the kind of guy to spend $550 on a belt.
Don't do it, people will either think you're a gullible fool who got conned or a tool who wants people to think he's loaded.
quality wise, they're probably the best I've seen and owned. the big H buckle is exclusively the province of douchebags, so I think you should just avoid those. Hermes does make different, more tasteful buckles that are good options. my Hermes belt is a "normal" looking buckle but I do love the craftsmanship (I believe the material is palladium)
The H belts are overpriced in an effort to keep the status or allure of owning one high. I love the leather, the fact they are reversible, and even some of the buckles are cool. But I don't really find them appropriate in most settings....too showy.
