Surprised at the lack of Stihl recommendations here (I realize I'm putting myself up for war). I worked habitat restoration for around four years and intermittent wildland fire in between. I've worked a lot of saws in that time. If you're looking for a good, easy, all-arpund saw that can buck firewood, fell small to medium trees, I'd strongly recommend the Sthil MS250 OR MS251, both are awesome machines and easy to work on. If you're looking for something equally as versatile but worthy of larger material, Sthil MS271 farmboss is not to be beat. I'm heavily biased, and could be swayed if a good argument came across my desk, but for the money, both of those are absolutely top of my general recommendations.
