Lionel 18119 UP Alcos vs. Williams Golden Memories UP Alcos?

[02camaro]

I have some of the Lionel 16068-16074 Union Pacific 027 yellow passenger cars from '94. I want to get a set of Alcos to pull them, but I'm torn on which to get - Williams or Lionel....Has anyone had any experience with either one? Does the yellow paint on the Williams match the Lionel cars?
