With power fist you get an additional attack only if you have power dagger too which only sergeants can take (consequence of the specialist weapon rule). So since you will strike at initiative 1 anyway with either weapon, you might as well choose power fists for the much higher strength value, however, that will reduce your number of attacks too unless you have a power dagger which only the sergeant can take. So suddenly it is not a no-brainer to switch out the axes for fists. What is your take on the problem?
The way you phrased the emphasized bit makes it read like youre losing attacks by swapping from Axes to Fists, with or without power daggers when thats not the case.
Squad of 10 with axes has 21 Attacks (2x9 + 3); 31 attacks on the charge.
Squad of 10 with fists and a dagger on the harrower has 22 (2x9 + 4); 32 attacks on the charge.
