a higher discharge rate should provide MORE punch..
every cell, no matter what chemistry, has an internal resistance to flowing current. If the int. res. is high it limits the current more and lowers the max. discharge rate (current).
The capacity rating (mAh) is not directly related to discharge rate, but you will often find the higher capacity cells are slightly compromised by a lower max. discharge rate due to a higher internal resistance.
I think.. 😛
