I've ran 2 and 4 stroke gas string trimmers, leaf blowers, and chainsaws most of my life. Based on my recent luck as a new in-town dweller with intermittent use, and based on using multiple family members (some large farmers) LiIon tools of multiple brands and styles, I am a full convert in the battery power is awesome camp. The only reason I see gas as better now is if you need the extra power for your job, or if your "off grid" for days at a time or working every day all day long.
If you occasionally need to fell a medium tree, clean up storm damage, weed eat a moderate yard every week or two, etc; then I firmly believe the new battery powered tools are where it is at!
You don't have to worry about having additional 2 stroke gas just for tools. They start and run perfectly after sitting, just pull a switch and it works. Compare that to pulling and pulling a pull cord on a tool that hasn't ran in weeks after sitting in the back of a pickup. They can be charged relatively quickly after a few hours work at home, in a vehicle, or by solar. They don't run rough and hardly start after sitting a season or two, they just sit there waiting and when you pick them up all it takes is a trigger pull and they instantly work.
ETA: I currently have a small fleet of Husqvarna, Stihl, Snapper, and Craftsman gas tools. As they wear and die off I will be converting to a common family of lithium powered tools.
