I have pretty much all that are mentioned. My favorite is probably the Atlas 40 footers. Can be found reasonably priced and with the diecast chassis they are nicely weighted.
My home road is the Rutland. They only rostered one OB Single sheathed car. Was a CN car they fished out of a river. I could have added decals to a production car and no one probably would have questioned. The car had wooden ends. Working just from photos. I decided to use a Mainline Models wood kit mated to an Atlas chassis. Sort of a Hybrid build. It won’t win any contests but it is different and a little more prototypical.
