MicroStation to Blender workflow?

I've seen a few posts show up in the search results for Blender. I'm wondering if anyone here has established a workflow for making MicroStation 3D Models usable in Blender?

What I'm looking for is:

  • Export Format
  • Export Settings (including any necessary working unit settings)
  • Import Settings within Blender
  • Additional initial steps within Blender (geometry cleanup etc..)

I recently did an initial test and the only file format format I had some success was OBJ but I'm about to make a more concerted effort and was curious if OBJ is still the way to go or if FBX or other is the better route to go down?
