I see some people reporting favorably about brands that specialize in outdoor power equipment. It reinforces a theory I have. That is, a company like Milwaukee, DeWalt, etc, that started out making drills doesn't do as good a job at making OPE (outdoor power equipment). It seems the companies that are doing a good job at it are using higher voltage (40+).
I think this is a good theory. I have Ego outdoor tools (string trimmer, chainsaw, blower, push mower) and DeWalt 20V hand tools, and am happy with both as a moderate-heavy use homeowner. The 18" chainsaw will do a solid cut but is a bit slower than a good gas saw. Since I am not breaking down big trees for hours at a time on the regular, I don't mind. Everywhere else it wins big. Battery life is good on everything except the mower, which does eat them up. I have 3 sets of batteries so as long as I charge them I am not going to run out in the middle of anything.
If I was starting over today I would shop the different systems. Ego was the right mid-point for me 2 years ago but not sure if they are still the best "prosumer" line today. It is definitely a "system" purchase because you want to be able to share batteries.
