And on a lower end mechanical disc brake+ lock end fork combo, the disc tab usually are not welded perfectly stright, resulting in the pad hitting the rotor at an angle, and again resulting in loss of power and efficiency.
My "street" bike is still running Avid SD Ultimate Vees on the rear with a hydraulic disc on the front for the modulation.

First off, avid ultimates are roughly 10 times better than your average v brake set.
I have been biking for 10 years, my main Specs are Downhill and Trials riding, i had avid ultimates like you and i changed them for Avid Code's, they have literrally saved my life on 2 different ocasions while biking through europe, where its a bit crowded. I do agree that most disc brakes are in general gardbage and not as responsive as a ultimate v brake but then again, the ultimates cost 200$ per set, so thats almost as much as a set of Avid Codes which are brilliant and have massive stopping power.
The main reason why i like disc's is that in boh trials and DH, bent rims are as casual as inflating my tires. With v brakes i would be stranded in most cases. And if it rains discs have the upper hand.
Ultimately its all about the rider, brakes are important but more so for newer riders who dont have developed reflexes. I've seen this shit first hand when a woman bikin on a city bike with obviously shit brakes went face first into the door of a civic, some will argue that its the Civic's fault but from my point of view its 100% the riders fault for having shitty reflexes ( BTW the Honda door fell of its hinge
