I've noted that a lot of folks on this forum ask the opinions of other members, most, complete strangers, other than forum chatter, on what they should buy. There are a lot of personal reasons for buying any luxury item, such as these trains, and those decisions may be best left to the buyer, because in the end, you are the one that has to be content with your purchase.
After collecting for maybe 5 years or so, my older hobby mentor told me once that I knew just as much, if not more, in some areas, as the respected experts, and I realized he was right. That's when I found I no longer needed help in those decisions.
These are newer items, so the preferences between road names and whether or not it's traditional or contemporary are purely personal preference, and not based on condition or collector value, as a general rule. A guy like me would default to traditional, and Allen would probably default to Contemporary. Both of us would do that every time, so you can find any answer you want to validate your own opinion (you have an opinion on this, you just may not realize it yet), or go against it.
Buy what you like, and remember that your opinion is just as valid as someone else's, and more so when it comes to your own collection.
