Agree on the convenience of onboard power. However, there are lots of Powerboost complaints on the Forums and FB groups. They were the least reliable drivetrain of F150 for the last few years, which is understandable as it was new. In the '24+Ford expects the Powerboost to increase from 10% of units sold, to 20% of units sold, so I imagine they've put a lot of work into ironing things out.
Also, a lot of '21-'23 Powerboosts (I've heard all and I've heard not all) came with the 3/4 float max tow axle, which is something to be avoided.
Lastly, if you don't do a lot of stop/go driving or really need the onboard power, I don't see a lot of benefit to the Powerboost. Like in the Toyota Tundra, the extra power is largely offset by the extra heft.
