Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Two whitelisted testers cover the DWE6421K, but only Reviewed hands-on-tested it, naming it Best Overall for stripping paint in about three minutes versus roughly five for rivals. It praises the powerful 3-amp motor, comfort and decent dust collection, while flagging single-speed operation and that the tool jumps and pulls. Pro Tool Reviews is a spec preview, not benchmarked. (2 sourced reviews, 1 lab-tested.)
Praised: Fast, powerful 3-amp motor; fastest paint removal in the test (~3 min); Comfortable to hold in multiple positions; Decent/quality dust collection, especially with a shop vac.
Flagged: Single speed only; Jumps and pulls; harder to control than rivals.
Only one whitelisted tester — Reviewed (USA Today) — hands-on tested the Porter-Cable 382, naming it best for dust collection. It praises near-cloudless dust capture with a shop vac and smooth, easy control (~5 min to strip a painted board), but flags the flat, uncontoured top handle as uncomfortable for long sessions. Single source; no cross-tester corroboration. (1 sourced review, 1 lab-tested.)
Praised: Excellent dust collection — bag lets out little dust, almost no cloud when paired with a shop vac; Smooth, easy-to-control operation good for longer sanding sessions.
Flagged: Flat, uncontoured top handle is uncomfortable to hold long-term.
