Got HyRds on the front and Spyres on the back of 2 bikes and find them good on balance. Don’t think they’re any better or worse than BB7s, just a whole lot easier to set up and fairly fettle-free, also better in terms of pannier clearance. Personally don’t think they’re any better than the V-brakes I’ve got except in the wet.
Had trouble with judder on the front brake for a while but copper grease and probably something else cured it mostly.
Also found it difficult to find the right pads. Last lot were squealy horrible. New kevlar ones seem ok so far……
