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).
Ridgid R8654B 18V OCTANE Brushless Cordless 7-1/4 in. Circular Saw
Only one whitelisted tester, Pro Tool Reviews, published a hands-on head-to-head review of the exact R8654B; no other whitelisted hands-on reviews were found. Their verdict: a solid brushless upgrade over Ridgid's Gen5X with excellent blade sightlines and shoe glide, but middling raw power (lowest of three power tiers in their test), a guard that hangs on thin cuts, and heavy weight. (1 sourced review, 1 lab-tested.)
Praised: Excellent, unobstructed blade sightline aided by LED; Magnesium shoe coating glides smoothly over material; Comfortable, well-offset handle with Hex Grip overmold; included vac/dust port.
Flagged: Lower guard hangs on thin shave, miter and compound cuts; Shoe notches off ~1/8 in at 0° and 45°, plus slight crosscut tracking wander; One of the heaviest cordless sidewinders (9.5 lb bare, 12.0 lb with 9.0Ah pack).
