Many thanks for your reply Norm
I went ahead and bought the NSS version of Wrangell (and Sitka) in the Marketplace Black Friday Sale... and I'm glad I did! the NSS version definitely contains more detail than DC Scenery Designs.
First, here are some of my screenshots from DC Scenery Designs version, staring with an overview of the runway and what appears to be a wooded densely area (with some random buildings inside) on the seaward side. Compare this area to the non-wooded area with detailed buildings and radome in NSS, shown later...
Here are some very generic building in the area up above and behind the airfield. Again, compare to NSS later...
This area looks very plain (not so in NSS)...
In this version the terminal is exterior only (NSS has a nice interior)...
Here are the remaining DC Scenery Design Shots...
