What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
MS 271 Farm Boss
One whitelisted tester covers this exact model: Pro Tool Reviews names the Stihl MS 271 Farm Boss its Best for Firewood Stihl pick in a July 2024 buying guide. It is a qualitative recommendation praising the workhorse value and improved air filtration, with no independent lab measurements reported for this model. (1 sourced review.)
Praised: Value workhorse firewood saw at just over $500 with a 20-inch bar; Improved pre-separation air filtration and half the emissions versus the older MS 270.
Flagged: Not the most powerful option; step up to a bigger saw if you need more power.
Pro 80V 18" Chainsaw
Only one whitelisted tester, Pro Tool Reviews, has a hands-on field review of this exact 18-inch 80V Pro model (GCS80420). It scored 8.5/10, praised for gas-like cutting power and rugged build, with short run-time the main knock. No tester-measured benchmark numbers were published (only manufacturer specs). (1 sourced review, 1 lab-tested.)
Praised: Gas-like cutting power; the 18-inch bar cleanly sliced 16-inch oak trunks; Rugged, gas-saw build feel — metal wrap-around handle and steel bucking spikes; Near-instant on-power versus competitors' start delay, plus quieter operation than gas.
Flagged: Short run-time on the 2.0Ah battery; needs spare packs for larger jobs; Heavy and hefty — not an ultralight in-tree saw; Can stall if pushed too hard into thick trunks.
