Worm drive vs. sidewinder: which should I buy?

Worm-drive saws (like the SKILSAW SPT77WML) deliver higher torque at lower RPM and a left-blade orientation that pros say helps with cut-line visibility on framing lumber; sidewinders (like the DEWALT DWE575 series) are lighter, faster-spinning and easier to handle one-handed for shorter cuts. Carpentry-subreddit consensus is that framers tend to prefer worm drive, while remodelers and DIYers mostly reach for a sidewinder.
