husky vs stihl
You should buy either husky or stihl. After that don't worry about it so much.
(Some Huskies from Eastern Europe are very very poor and some huskys in the bigger store in the US aren't made by Husky. Also some stihl imitations are made very poorly in china. So stay away from that stuff of course.)
One thing to note is how much the two brands are coming together more and more. Design-wise; they are looking alike.
With regards to maintenance, the three most common maintenance items are; 1) Gas and oil, 2) Bar and chain and 3) air filter. Look each over carefully and these three items might be the reason you select one saw over another.
{One thing I noticed about huskys in the late 1980's and early 1990's was that husky had more problems with parts. They did at least double the correction/upgrade on their parts schematics that stihl would do in the same time frame. It sure seemed like stihl spent a little more time on design and manufacture than husky. This is very annoying when you are the guy in charge of maintaining 30 large huskys)
Dealer support is probably the biggest item. If you have one dealer that carries both, be aware that at least in the states stihl supports its dealers better than husky does theirs. It is not just the big box store sales, when stihl has a sale, they absorb most or all of the loss. Husky makes their dealers eat it to a degree. This can be part of the reason a dealer may favor stihl. I don't know if any of this is true in Italy.
I favor stihl, but don't have the recent experience with huskys that should be required to actually give a recommendation that would count.
I would suggest that the competition between these two large manufacturers is very good for us.
All the Best
