The poleaxe is a terrifying weapon, used properly. Pole arms in general have an advatange: range. Keeping thy enemy far away is pretty much always better.
There are some of the Masters that refer to the mere quarterstaff as the prince of weapons. They often waited until a student had mastered the study of longsword and all other weapons first. Showing mastery of everything else then they would demonstrate and teach to the student the quarterstaff.
Properly done, the simple staff can defeat all others.
I found that out when I read the 'Tales of Robin Hood, more than 50 years ago.
Actually, it's a buck-and-a-quarter quarterstaff...
