So, in general and all things being equal, you feel the non-xdrive transfer case would fare better when it comes to using mismatched rolling diameters in the front vs. rear? I'm probably missing something and don't know it.

An old pick up or Jeep has a locked up transfer case in 4wd, simply dividing the power front rear but not allowing any speed difference. That is a very different type of transfer case.
I don't have data to back it up, but yes, for the following reasons
*The non x-drive (nxd) is an open diff. It can handle speed differences
*The xd has clutches to wear
*The X3 (which only came with xd) had more problems with transfer case failures, attributed by BMW to the use of different sized tires.
*BMW has a towing limit, with one axle raised, of 150 km at 50 km/hr for the nxd. Towing the xd with one axle raised is not permitted due to the risk of transfer case damage.
