It was the only pro saw the OP asked about. All the others, are rated as farm use.The 261cm is a metal cased saw .............and the only pro series saw you have listed also the one i would choose ........
Stihls way of saying they're midrange.
And there's nothing wrong with farm use.
A lot of tree services use MS250, MS291's etc etc.
The chipper and skid steer doesn't care when it eats or runs over a inexpensive saw or a MS500i.
