DPE is a cheaper alternative to HRE or VIP Modular or ADV.1 etc. Rotiform is way up there too though, I've seen $8K for 22" wheels which is up there.
Honestly, there isn't a huge advantage to 3 piece wheels. Basically the 3 pieces are the face, the outer barrel, and the inner barrel. The inner and outer barrels are bolted together and then sealed. A 2 piece wheel has the face and the barrel which is one piece. The only advantage of a 3 piece wheel is that there are a huge number of options when building the wheel for brake clearance, style, etc. A 2 piece wheel has most of those advantages but has slightly less options because the barrel is one piece. The downside of a 3 piece wheel besides cost of course is that the 2 piece barrels is another place for air leaks. Not common, but it happens.
Also, 3 piece wheels aren't always stronger than one piece or 2 piece. The center is usually forged which is stronger, but the barrels are always cast and that's the piece that takes all the damage. Only way to get forged barrels is a forged monoblock wheel like a Volk TE-37 or similar. FWIW, a lot of multipiece wheels have cast centers as well like Work. Only upside is that if you damage a barrel, you can replace just that one part instead of the whole wheel. And if you ever want to change up your wheels, you can have them rebuilt like Rookie did when he widened his HRE's. They just unbolt the barrel and put a new one on.
I have 3 piece Forged1's on my BMW. They're beautiful and the detail on the face is amazing; they're maching perfectly to match the barrel. And the hardware is all hidden along with the valve stems which are on the back side. But they came with the car, otherwise I would have never paid the $6K+ for 20"s with tires. Not on a daily driver; that's just me though.
So long story short, multipiece wheels offer a look that you can't get from a one piece. Yes, there are reps, but put a rep next to the real thing and it's very obvious. If you like the small details, you'll probably like 3 piece wheels. If you just want 22"s, there are much cheaper options. If you're looking for 3 piece wheels made in America that aren't HRE, just shop on price. They all get the barrels from the same place and most of their styles are very, very similar. ADV.1 charges a premium over a lot of the other companies but it's all marketing and it's just a new name for 360 Forged which was an early company in the "lifestyle" 3 piece wheel game and who scammed a lot of people who paid a lot of money. It's a very incestuous business; notice almost all of them are based in Miami?
