PC-E 24 on D800E vs TS-E 24 II / 17 on 5D II (or III)

This inspired me to compare the following:

1) 5D2 with 24TSEII, three image portrait orientation shift-stitch corresponding to 17mm equivalent field of view (36x48 format, no resampling).

2) D800 with 28/1.8G, four image stitch to match the 17mm field of view (resampling necessary for stitching).

I honestly don't quite know what to expect from this test...

The 5D2 will produce a 42MP image, the D800 will have more than twice as many, however resampling is involved.
