I have run both Stihl and Husqvarna. I am currently Stihl only. I have a big wood furnace and so I cut a lot of trees. I have not had one issue with my Stihls, but my Husqvarnas were OK too, for the most part. I have ms260, 250, 361 and a 441. All have their place, but for a small saw, my muffler-modded 260 is hard to beat. It starts easily and does well, within its limitations.
My kid is a wildland firefighter and he is a saw guy. They gave them new Makitas (Dolmar) last season. The saws cut well but have a terrible chain brake setup. They broke very easily.
If you are not going to be cutting anything very large, then a 50cc saw with a 16-inch bar will do. Gauge the saw on how much cutting and how big that you intend to do. Get a pro-level saw if you can afford it. Most home-owner/ranch class saws are alright, but the pro-level saws are just a better investment. Get the biggest saw that you can handle, for the jobs that you are doing (and afford). There are two things that you should do, no matter what kind of saw that you end up with.
First, run non-ethanol fuel in it-preferably premium. If you have to run ethanol, then do not leave it sitting in the saw for long periods.
Secondly, learn how to hand-sharpen your chain. If you take it to someone that uses a grinder, the chain will not last as long as with hand-sharpening and if the person is an idiot, he will actually burn the cutters on the chain. A sharp chain makes a good saw out of a mediocre saw.
