The burris has slightly better glass (actually better coating) than a rifleman.
The burris is a 1/4" positive click adjustment, rifleman has (i think) friction turret adjustments.
That said, I've had both and preferred the rifleman 2-7x33. I found the rifleman eye relief to be less critical, and faster to find the target than the burris FFII 3-9x40.
I think it's a given that Leupold warranty is the better of the two.
