Our take
When Reddit's r/Dewalt says 'the flexvolt circ saw is in a league of its own — truly a different tool than its 20V counterpart,' that's the kind of consensus you can bank on. This is the cordless saw for people who don't want to compromise.
For anyone not on a job site daily, the Ryobi HP is the sweet spot — you get brushless motor durability, a full 7-1/4" blade, and compatibility with every other Ryobi battery you own, all for $139.
