I agree with the looks improvement. It seems Murphy guides my fate in life and some of those nice looking castings are soft and mine end up bent. So I try to stick with what can take a drop or a trip over or a cat whack. That is why only plastic tumblers at my house, no glass.
One time when ordering some Hartland parts for projects, I chatted with Phil Jensen. He told me some commented on the lack of fine details on his models. He said that he had been to so many layouts where there were broken cars and broken parts laying around and he decided durability was his goal over fine detail. I told him I agree with that, especially when dealing with models that will be used outdoors. That is why I avoid USA trains, the more fragile parts.
But as I always say, to each his own. Do what you like and works for you.
