I saw in the 2017 Lionel catalog that they will be offering a PS-1 boxcar in their LionScale line. I am assuming that this will be based on the Weaver offering that they acquired. It made me wonder how the four manufacturers' compare. My gut feel is that in descending order of fidelity it would be Atlas O, Lionel, MTH and then Weaver.
I am hoping that this thread would generate some qualitative comparisons.
