I like the RC racks best. The panels have a realistic ripple effect when you look through the sides. I think MTL could also achive this if they used a see-through plastic core. That being said, the RC cars are slighly long, while the MTL cars are narrower and taller. I think the RC cars look the best. I am experimenting with NWSL 28" wheels to lower the MTL cars, but have not yet figured out how to raise the couplers back to the normal height.
