I don't know how the pre-2020 acceleration ranked, but I can rank my 2020.
Fastest to slowest acceleration: D, B, D + Eco, B + Eco, D + ePedal, B + ePedal
If you have LeafSpy, you can see a slight power difference between D & B modes provided you can hold the pedal perfectly still and have a smooth, level road to drive down while you flip between the two modes. ePedal mode basically destroys the acceleration by limiting it to under 80 kW from what I remember. Eco mode didn't seem to have any affect on ePedal mode. This is all from memory, I could do a more controlled test to make a better list if the demand was high enough.
