Quote: "witch program works best with DARK Basic"
To accurately answer your question, none of them do - a 3D modelling program is only used to create models for DB.
To answer what you probably mean, then ANY 3D modeller will work as long as it saves .X model files.

This suggests that you should have asked which is the easiest one to use. Unfortunately, that's even harder to answer because they all work differently. I swear by TrueSpace but anyone who has used any of the others would probably hate the interface.
Gamespace Lite is the free cut-down version if you want to try it.
Others like Milkshape or Blender. You need to try them yourself to find out which one you like the best. Just remember to make sure it saves out .X files...
