Husqvarna, definitely. I have a Stihl that would make a wonderful boat anchor, and a Husqvarna that will start and cut no matter what. Also, I used to work for a motorsports dealer who also sold and serviced both brands... and easily 90% of the repairs which were brought in were Stihl.
The Stihl brand is considered a better chainsaw brand as compared the latter by users. Stihl produces a number one selling brand of chain saws and a full line of outdoor power tools including blowers, trimmers, brush-cutters, and construction.
