Me, I'll play the original, or one of the DOS-based ports. I did work on some smaller non-ZDoom ports so if I want to play my own levels or such I don't have an option!
I'm not following. The screenshot is basically jDoom engine and the maps are originals, only the textures are replaced with higher-res and sprites with 3D models. If you disable the fancy stuff it'll look like the original and it will load any map made for the original Doom. Unless your port isn't compatible with the original, the maps should load with the other ports as well... I think.
