It's a win win situation. You absolutely can't go wrong either way, and any differences in specs you find are insignificant.
I have a Brown 472 (predecessor) to the 416, and would (will) stay with Brown Manufacturing. They're customer service is excellent (which really doesn't matter with an implement like this but still nice). They're background is in super heavy duty long lasting commercial mowers.
Unfortunately, they no longer use USA made gearboxes, but at least they were the last of the manufacturers to switch. They held out as long as they could.
BH is excellent also. Keep in mind, BH sells a light duty version which I wouldn't give you a dime for (the squealer models). Brown doesn't even offer a light duty version. The 416 is they're lightest duty and is a lifetime long mower purchase.
What is the price you are quoted, and is it with front and rear chains?
My next purchase from Brown will be this cutter....
TSG-2 Tree Saw with Grapple | Brown Manufacturing | 8 -633-89 9
Again, nothing they make is light duty.
