I get asked alot what are the best saws. My answer is the same as yours Magnus:Silvadavid.
If you are still here...
I think the brand is not you issue, rather lack of experience, knowledge, good dealer and support..
Regardless of brand a good dealer is priceless.
The good dealers might not have the shiniest store, but I bet you know when you have one!

What? Just tell them Stihl. Hands down.
Not sure of details about what's covered, but the 5 years is for a homeowner. Commercial use is 1 year warranty.
If you have a Stihl that needs a warranty job inside 3 months, you either haven't purchased the right grade saw for your work, or you've bashed the shit out of it.
