My recumbent has V brakes and stops fast enough to give you whiplash as does my XC mountain bike... XT dual pivot brakes with Kool Stops is more braking power than my 145 pound butt requires.

My Kona downhill bike has discs, it also stops on a dime and gives back a nickel change.

I tour with cantis and V brakes and ride cantis and V brakes all winter long.

My road bike has Ti centre pulls... it stops in a hurry and I can lock it up at any speed.

Upside to hub brakes of all kinds is reduced rim wear and consistent all weather performance, swapping the disc pads on my Kona cost less than replacing my V brakes on my XC bike.

Disc brakes are also very easy to service, after the initial set up and bleeding hydros are the easiest brake system to dial in.
