IMHO both are not in the running for my money... for me it's either of the following:
Fixed barrel:
HW 97 / HW 77
with V-Mach FAC kit... though I have been hearing that the new HW's quality isn't as good as the older ones, but still they are extremely well made airguns.
AA TX 200 / AA ProSport
Break barrel:
HW 80 aka Beeman R1 with V-mach FAC kit
rest it's your dime....
For the power hungry who would sacrifice accuracy, I can only say - chuck ariguns and get yourself an IOF .22 LR rifle!
