I guess SoW is somewhat unique in the flight sim department in that it supports self-shading for aircraft interiors as well as exteriors (RoF also has this feature).
However, I understand why the DCS team would have chosen not to represent these - the cockpits of modern jets are very busy, and they would obscure the fine text and markings on the panels. It's very much a technical simulation than a graphical/arcade one.
The terrain detail is far less than that of SoW so far, but you can't help but like the colors and photographic textures.
