What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Bosch CS5 15-Amp 7-1/4 in. Left-Blade Corded Circular Saw
Only one whitelisted tester, Pro Tool Reviews, covers the Bosch CS5, and it is a brief 2010 first-look preview rather than a hands-on lab test, so no independently measured numbers exist. It praises the left-blade line of sight and calls the 15-amp saw one of the best values; no critical testing or negatives are available. (1 sourced review.)
Praised: Left-blade orientation gives a clear line of sight for accurate cutting; Regarded as one of the best values among 15-amp circular saws.
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).
