For reasons that make me question my own sanity, I wound up with one each of the Lionel and MTH versions of the UP/Rio Grande Heritage SD70 diesel. I only want to keep one. I'm posting photos of both, intentionally not labeled to eliminate brand preference, and asking which you prefer and why. For those of you who have one or the other, or both, what's your experience, which do you prefer, and why? Thanks.
I don't see a lot of difference, myself. The most noticeable differences to me are the color variations, and the fact that on one the cooling fans are gray and on the other they are black.
Here's a shot of both of them, nose to nose. I will call the one on the left Loco 1 and the one on the right Loco 2. The colors on Loco 1 are lighter, brighter, and purer than those on Loco 2. The gray on Loco 2 is a bit darker and seems to have a very slight greenish tinge. The yellow has a touch of orange and is also darker than Loco 1. Which do you think is more prototypical?
Here are three shots of Loco 1.
And the same three angles for Loco 2.
