Brian, your restored, repainted and renovated trains look great.
Although I prefer O Gauge with 031 and wider curves to 027, I also prefer traditional sized trains to Scale sized trains because of my medium sized layout (35 feet long and to 3 to 4 feet wide around the walls of 2 rooms in my basement). Traditional enables me to make trains with more cars to traverse my reverse loops.
Now if I had a large layout (50 feet by 20 feet or larger without reverse loops), then I would go for scale over traditional. For instance, I recently became a member of NJ Hi-Railers Club (layout is 185 feet by 30 feet without reverse loops) and scale size with huge locomotives and trains with 50 plus cars looks awesome.
