Worm drive or sidewinder: which corded circular saw should I buy?

Across the reviewers we read, sidewinders (in-line motor, like the Makita 5007MG and DeWalt DWE575) are lighter and easier to maneuver for general cutting and overhead work, while worm drives (like the SKILSAW SPT77WML-01 and Bosch CSW41) trade weight for torque and a blade-left sightline that framers prefer for ripping wet or thick lumber. Community consensus is that either format will serve most users; the choice comes down to weight tolerance and whether you cut a lot of dimensional framing lumber.
