Having used V, then dual-pivot callipers, then disc, I can say that my preferences are definitely the reverse order of that!
The issues I've had with V's over the years are always the same: one of the two levers gets a bit stickier than the other, which means I have to disassemble the whole thing, grease it, and try again, but by that point, the other side is too sticky, so I have to do that all over again too.
The dual pivot calliper has never given me those issues. It just works. If it comes out of alignment, I give it a whack to the appropriate side, and it's fixed.
The discs, OTOH, are wonderful: they don't leave brake residue all over the place when I ride in the wet.
As for fettling: switched over the tyres to the new studs that I picked up on offer at the beginning of January, so that I can run them in for a couple of days and be ready for the next day with black ice.
