On the motorway sections of the X21 the ride was buttery smooth and you could barely hear the engine, so I'd imagine it'd be the same over that way.
Not personally, but my friend who's on the X9/X10 rota said it does 60mph up the bank passed the old Sunderland Echo building on the A19, so it sounds like it's quite decent on the route. Mind, the same might have been said about the B9s.
