Jonsered has kind of a "cadillac" image in my area; premium saw at a premium price. Whether that's good or bad is probably a personal perception thing. Most everybody seriously shopping for a chain saw notices the similarity between the Husky and Jonsered lines, and sometimes may find Husky models at a better price than a similar Jonsered, but serious shoppers also soon notice that Jonsered seems to be inhabiting the little guy shops, while Husky is everywhere including the big box stores.
For me, that is Jonsered's appeal; that and the nicer-looking color scheme. There's something about the color of a Husky...looks faded and worn, even when new.
I currently own 4 Jonsered saws: a 621, 625, 670, and a 2149. I have owned a 2055, 2081 and a 70E, and can say I've been pleased with every one of them.
