Well, I have been a Stihl guy for over a decade, but I must admit the ebz 8500 blows more air than the BR 600. And not just by a little bit, it seems like 20% or even more. The Stihl in my opinion is only superior in (2) areas, comfort, and fuel consumption. The Redmax is a BEAST with leaves. It moves massive piles of leaves with ease. If you do one time clean-up's, this is the machine for you. I have yet to get into a situation that this machine can not just over power. We only do .5 -- .75 acre lots, and we can blow from the back to the curb with no issue. The EBZ has a much wider pattern, which took a tank or so to get used to. Since the Stihl necks down the end tube for more CFM, it blows a much more narrow pattern. I'm a convert, ALL HAIL THE REDMAX EBZ 8500!!!!!!
