I purchased Cinema 4D XL exactly because MOI exports (obj) looked in Cinema 4D exactly like they do in MOI!

This is of course keeping the normal tags exported from MOI but even if you remove the tags the objects still come in clean and work very well with C4D. ;-)

Not an issue. And for more complex import options there is the free riptide plugin for .obj files.
I do a lot of work with the VRay plugin for C4D and encounder -zero- issues.
