It is an interesting aspect to production runs of any internal combustion engine that they are not all identical in output. Y'all might recall that I have two 200's...a T and a rear handle. They are close to the same age, both fully broken in and fine, reliable runners. But there is no doubt in my mind that the rear handle has an clear edge on power...and I run a 16 in. bar on it, while the T carries a 14.
Some have suggested that the ergonomics of the rear handle might make it appear that it cuts more strongly, but I've concluded after really trying to make a honest comparison that the RH just pulls better. The T is no slouch, but that RH is an animal. I've had cutters working near me when I have been running it ask what I've done to it, just based on the exhaust tone and the speed it cuts and the roostertail it throws...I've done nothing other than pull the screen (as with the T), and I'm convinced it cuts at a noticibly higher level of performance.
