You stated between 10 to 20 hours a year of usage. I would without a doubt in my opinion, not be hesitant at all to purchase the Husqvarna.
Husqvarna makes a model that is about the same but just a tad bigger and quite a bit more expensive. Seems they try to call it more of a pro version.
We have purchased a few of the T435's with extra bars and full chisel chains.
Two of them have 60 hours plus on them this year already, since new without a single hiccup. They have been worked pretty darn hard. They do use bar oil and gas. They rev high and blister through wood relatively well. We have northern trees up here in MN.
The key to longevity and production is to clean them often when they get used. Never ever run out of bar oil EVER. Clean the air filter after every use or more often if used for longer than an hour. Make sure to adjust the carb on them after a few tanks of gas (non-ethanol aka regular gas if you can get it) either by you if you can do it right, or your dealer. The dealer should just do that carb adjustment for free. It takes only a warm engine and a minute or 2. Also buy extra chains if you are not into sharpening often. Sharp chains are one of the most important factors to a well running chainsaw.And buy or barter your way into a case for it. The Husqvarna ones aren't cheap but well made. Or just buy the same size poulan ones for even cheaper(Husqvarna owns poulan). We keep 3 chains, an extra airfilter, a bottle of bar oil, an extra bar, a bar sprocket tip oiler, an extra spark plug and the sharpening kit. The carb adjustment screwdriver and wrench/scrench that came with the saw also stay in the case. It will all fit in there.
I have and have run a few models of Stihl. I currently do not use any of their products. I've had more issues with my Stihl products than I ever have with our Husqvarana products. Our company is all Husqvarna for quite awhile now. In my opinion and experience I do not vouch for Stihl anymore.
So far like I stated we have had outstanding service with Husqvarna machines.
Good luck and have fun and stay safe with whichever purchase you make!
