The Vulcan handled like a fighter, despite its tennnis-court dimensions. The others handled like airliners. And in a display the 4 Olympus engines would crush your chest as the air pulsated and turn your feet to jelly as the earth vibrated.
Speys? Pah!
That's why a Vulcan display (a real one, in pre XH558 days) was something you'd never ever forget.
