Besides the difference in sensor sizes for the tests (one being APS-C and the other full frame), I am sort of wondering why you want to compare the sharpness of those two lenses?
The focal length, and therefore the field of view, is quite different... So much different that that is way more important a difference than which lens is sharpest...
Both lenses anyway are sufficiently sharp. The 50mm f1.8 is alround a good lens, I am a little bit less impressed by the 35mm one in terms of bokeh smoothness and CA performance.
Determine which focal length is most valuable for you (the 50mm being more a short almost portrait lens on APS-C, the 35mm more a normal shoot-everything lens), and base your choice on that.
Slight differences in sharpness are not noticeable in photos, but the big difference in field of view is very apparent.
