From a guy who owns a handful of gas Stihl saws (and uses them all frequently for my work) My go to for average stuff is a Stihl electric with a 14" bar. Not sure of the model (it was the fanciest one available 3-4 years ago.) Also get the nicest battery.
Sooooo nice to just be able to pull the trigger and go....let go of trigger and it stops. Lightweight too. Only issue is cause you never have to add fuel...easy to forget to add bar oil.
On a side note, I run skip tooth chains on all my saws. Keep em sharp and the batt saw will perform very close to a comparable gas saw with standard safety chain.
I cant say enough about how much I love that saw!!!!

My next truck saw will be one.👍
Ive actually filled an 8' truck bed to almost the top of canopy with 3-4"diam. pecker poles, prolly 75-100 poles, lots of bucking/cutting, still had 1/4 battery power left. Obviously not the best saw for heavy work, but all around my fav.
Elec saw is a 220c with a 300ap bat.
My fav gas saw is the 211, small but mighty with a sharp skip tooth. Dropped this walnut with a 310, but 90% of clean up work was the 211.
