I'll have to disagree with you on this. I have over 100 ore cars from all the manufacturers. The MTH car is taller than the others and IMO has the crudest detailing. Especially note the gears that open the hopper doors and compare them to any of the others.
The Lionel car is noticably narrower than the other cars, and narrower than the prototype. It is the smallest. The mold detailing is better than MTH and decoration is decent.
The Atlas (1970's production), K-line, and RMT use identical body molds. They are O scale sized and have the best detailing. The difference between the 3 manufacturers is in the trucks and decorating.
The Atlas car sits at the most prototypical height, however the trucks are plastic and the decorating is plain jane. I do have a lot of these that I bought back in the day. In the process of repainting them, haven't changed the trucks yet.
The early K-line cars use Lionel style plastic trucks and sit ridiculously high on the track, and the decoration is just so so. You would need to replace the trucks on those. I found a number of these at a really cheap price, repainted them and replace the trucks with Weaver trucks. Still sit a little higher than the Atlas cars but MUCH BETTER than the way they were.
The later K-line cars are on lower diecast trucks and have pretty good decoration. The RMT cars are also on diecast trucks and sit a bit high, but have the best quality of decoration and added detail.
I would recommend the RMT ore cars and the late production K-line cars as being the best of the bunch.
