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.
If you can stretch the budget, the Milwaukee M18 FUEL is the circular saw you'll never need to replace — it's what contractors actually use on job sites, and it shows in every cut.
