Wet debris, MPH is more important. Dry debris, CFM is more important.
Both your backpack and your billy goat are 200 mph but the 18 hp walk behind is probably 5 or 6 times the Cubic Feet per Minute. So it will move a lot more debris/bigger piles, which you are seeing.

The Hurricane and Brown claim around 6-7000 CFM I guess. That may be twice as much CFM as the Billy Goat walk behind. Hard to say because they seem to be avoiding a specific number of CFM with these high volume machines.
