To me, numbers really don't matter as much as simplicity & reliability.
I ride my e-bikes for commute with subway, ferry/bus transfers or transporting bulk & heavy food items.
For commuting e-bike, I need them to be compact, take up smaller spaces when not in use.
For transporting bulk & heavy items, I need my cargo e-bike to be trouble-free even ignored.
Power output & range is mostly secondary, since most my rides are within 30 mile range between location with charging capability.
