Yes the powder is cheaper but after a year they tend to start chipping away. Which is fine cause you can just recoat them, but then it starts to cost more than getting new rims.
Depends if you know if you're going to have to buy some new rims soon anyways.
P.S.
Don't get black for your YZ, they are way too popular, if you want to stand out and still look badass, get blue! (Those look way better than black in my opinion)
