If your going for a show of what a program can do then here-


- That's Blender. The boxcar took less than two weeks to model.
Or if you want to look at it another way, the most coplex steam model for RailWorks (In terms of what the engine can do)
http://store.steampowered.com/app/65222/ Was made in Blender.
That's not really how you want to go around looking at though. I used to use 3d Canvas Pro, but the I switched to Blender. I would recommend Blender, it is quite a bit faster than 3D Crafter, and I feel it is better. One of the reasons I feel so, is that you can map a texture to a model a lot more accurately than in 3d Crafter (Which is very important, for reasonably complex models, I feel). You do also get shadow baking, a nice plus. And did I mention it's free?
