Hi Vfr400
i have swapped over the batteries and it does not make much difference.
The hub motor seems smoother on take off compared to the mid drive seems to launch then top out.
I run a Garmin edge 510 and see the data live so my cadence is usually between 70 - 85 rpm
The hub seems to give a higher top speed this may be due to the difference in gearing, the mid drive as you say is more torque'y
At the end of the day it gets me out riding its just frustrating the mid drive eats more power
