I understand Shanghai traffic. For these trips though there's no need to switch airports. (Although that is an option if I wanted). I'm basically trying to find out how SHA compares to PVG. I'm not worried about traffic, and the hotel is stay at in Shanghai us actually closer to SHA, then PVG. Thus not worried about overnight needing to sleep.

I will save I'm impressed that even on shirt haul routes MU runs wide bodies to SHA, when they run single aisle to PVG. Alone that gives SHA an edge. However if it's a heckish airport especially for I-D and D-I connections then that doesn't matter.
