In our country, Husqvarna has the best dealer network.
Most dealers have mechanics.
Unfortunately, the same does not apply to Stihl, in my town there are two Stihl dealers, one is an agricultural shop where they do not do much chainsaw repair, while the other is a bicycle dealer. In fact, I think the bicycle shop has more knowledge of chainsaws. But the agricultural shop is good at having almost all the Stihl chainsaws.
Echo has never had a dealer network in Norway, there is an importer but not many stores.
When Husqvarna chose to dump Jonsered to the hardware stores, most Husqvarna dealers chose not to take warranty work on Jonsered. I know that Husqvarna asked several ex Jonsered dealers if they could.
