I suppose because I grew up with cantis, I've never understood the difficulties that people have with adjusting them properly.
I like my CR720s. Unlike a sidepull, I don't ever worry about the tire/fender clearance. With a V-brake, I wouldn't be able to use my VO Randonneur rack and Berthoud frontbag because the placement of the rack & bag would interfere with the tops of the brake arms and the cable routing.
Are they the strongest brakes out there? Maybe not.
Do they stop my fat arse coming down a 15% grade with a 45mph 4-lane crossing at the bottom? Yeah.
