Ed,
I don't have experience with both of the manufacurers, but have a few things for thought...
Since you are running some more modern stuff (Amtrak) it wouldn't be unreasonable to see buildings that have varying eras of pedigree and or style.
Look around at any town or city that has been in existence since the 1800's (or early 1900's), and you'll see a variety of styles, shapes and sizes.
In the early 1900's (and earlier) 9' - 10' ceilings were fairly predominant. That alters the total height of a building.
Additionally, before wide spread use of electricity, many buildings had lots of windows to take advantage of natural lighting.
Now if there is a distinctly noticeable difference in "scale", you can also group one brand of buildings in one area, and the other a bit further away.
By putting the larger buildings in the foreground, and the smaller ones towards the back, you are acheiving an effect of "forced perspective". This makes the smaller ones look like they're further away than they really are.
I guess what I'm saying is, if you like the buildings, get 'em, and sort it out later...
