Greenworks 80v saw, 18" bar, cuts anything and everything I throw at it, including trees thicker than the bar is long. My use is so occasional that a battery saw made far more sense than getting another gas saw.
Pluses:
Quiet. When felling, I can hear the first crack of the trunk. I also need no ear protection, so I can hear others nearby just fine.
Zero vibration. There is no gas saw that does not vibrate, due to the reciprocation of the piston. I can run my saw for hours with no numbness or tingling in my hands.
Starts first time every time. No comment needed.
Minuses:
Cost. To get into the system the way I wanted, I bought the saw, four batteries, and two chargers, an investment a little north of a grand. Most of the time I don't need more time to cut than one battery covers, but for the occasions where I do need to go beyond, my setup allows me to cut non-stop. I also have their trimmer powerhead that uses the same batteries.
Run time. If you have just one battery, the max I can get with regular cutting is 35-45 minutes. Constant cutting gets about 16-18 minutes. Rarely a problem for me as I usually cut, move logs, cut, move limbs.
Power cutoff. I actually have two saws, and use both. The first one I got has a limit on the time the saw stays on without using it, about 15 seconds. This is not dangerous, just annoying. The second saw stays on much longer.
I looked at Greenworks, Ego, Echo, and Stihl when I was considering this. Overall, the Greenworks came out on top.
If I had to do it all over again, I'd do the same without hesitation.
