What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
DeWalt DCS570B 20V MAX XR Brushless 7-1/4 in. Circular Saw
One whitelisted hands-on source (Pro Tool Reviews, 8.1/10) was verified for this exact saw (the review's spec table names Model DCS570B, the bare tool). Over several weeks of cutting plywood, rough lumber, PT and MDF, the reviewer calls the DCS570 a legitimate corded-sidewinder replacement with smooth bevel detents and a fast electronic blade brake, and standout value, while flagging the push-in trigger safety and the absent rafter hook. (1 sourced review, 1 lab-tested.)
Praised: Legitimate corded-sidewinder replacement; keeps pace cutting 3/4-inch plywood and rough 2x6 lumber; Smooth depth and bevel adjustments with 22.5 and 45 degree bevel detents; Fast electronic blade brake and comfortable contoured handle with offset pommel.
Flagged: Push-in trigger safety; reviewer prefers a push-down style; No rafter or belt hook; Runtime limited versus corded (need to cycle two batteries on the charger).
Skilsaw SPT77WML-01 15-Amp 7-1/4 in. Lightweight Magnesium Worm Drive Circular Saw
Only one whitelisted tester—Pro Tool Reviews—had accessible review prose for this exact model, naming the Skilsaw SPT77WML its best corded worm-drive circular saw for its 77-series 15-amp power and lightweight magnesium build. No other whitelisted source with accessible measurements was available, so no cross-source comparison exists. (1 sourced review.)
Praised: Named Pro Tool Reviews' best corded worm drive circular saw; 77-series 15-amp motor delivers ample wood-cutting power; All-magnesium housing (motor, shoe, gear housing) keeps it lightweight (~11.5 lb without blade) for a worm drive.
Flagged: Premium price positioning ($199, or $219 for twist-lock cord).
