Moto Metal 951s, Why Take 'em Off?

I've noticed that a number of posters here have had the Moto Metal 951s, and then swapped them out for other wheels. So....why? I think they look awesome, but maybe they don't look as good in person?
I really want these, but I am concerned by all the Taco owners that seem to ditch them.
Then again, maybe it's only GAS (gear acquisition syndrome) that makes them switch.

 

Because they don't all want to have the same rims. Although they may be common, I've seen more on Tundras than Tacomas down here in Fla.

 

I've never seen them up here in VT, but then again, I haven't seen anything other than stock rims at all here. Guess I'll be a trailblazer...so to speak, of course.

 

I had some and i loved them, but i needed new tires so i traded the wheels for new tires and wheels.
