I would consider all things other than aesthetics to be performance but I should have been clear. As for a list: strength, build quality, ability to balance well, durability, finish quality, ability to hold a bead well at lower tire pressure, customer service, and maybe characteristics that I haven’t thought of. I have never owned any of these brands. Thanks for the question.
I would think one of the wheel resellers would be able to answer this questions best.
That being said if the wheel meets US standards than it should be as durable as the next wheel that meets the same standard.
I guess finish and support would be a variable but I wouldnt expect to deal with support unless there is an issue.
Case in point I bought some Vossen wheels for a previous vehicle and I noticed the finish started peeling on one within a few hundred miles.
I sent that one back and they recoated it for free. Maybe two months pass and a few hundred more miles I notice the peeling on all four wheels.
I sent them all back and they again recoated for free and I asked them to cover my cost of mounting/dismounting which they did.
As soon I got them back I sold them because there's an obvious issue if this has happened twice and I didnt want to be their test dummy.
Other than the above example Ive never contacted support for a wheel and finishes have all been pretty good.
Just on this truck Ive have KMC, Method, Kansei and now RTR and they all have mounted/balanced just fine with good finishes.
The variable being the load they support. Pay attention to that if load concerns you. I believe the Kansei supported 2100 where the RTR's are 2500.
Oh and the RTR's weigh ~24lbs while KMC/Method were around 30.
Weight is important to me since the wheels directly affect acceleration, braking and gas mileage so to me lighter is the best option as long as it's equally as durable(safe).
Hope this helps.
