Dangerield is a more impactful player and more versatile but does more clamgers/poor disposals and has poorer leadership skills. Depends on what you want a leader and a competitor or a bull who might win you games off his own boot. Given we've won 3 and he's won none I think the answer is clear. Bulls can get stopped, even great ones, leaders still lead.
Actually as far as bulls are concerned I'd take G Ablett Jnr over Danger at their peaks. He was untackleable and didn't do clamgers. But I'd take Ling as a leader over Jnr.
