Dorn was more steadfast, controlled, reliable & sensible. Perturabo was more flexible, creative, ruthless & savage.

Dorn was also more rigid, less imaginative, dour & stubborn. While Perturabo was bitter, prideful, temperamental & small minded.

As for their Legions each followed in their primarchs footsteps, the Iron Warriors were ruthless & creative killers but were riven by back biting & internal conflicts. While The Imperial Fists were steadfast, determined & implacable but were also inflexible, predictable & narrow.

Who would win in a conflict would depend largely on whether the Iron Warriors managed to find a way through or round the Imperial Fists defenses before their internal divisions or a rogue cowboy officer left Iron Warriors open to a crushing offensive thrust from the Imperial Fists.

As for the primarchs themselves as far as I know they never met in combat during the heresy & when Dorn was killed by Perturabo (theoreticly) the Iron Warriors primarch was by then a demon prince & so much more powerful than Dorn that the Imperial Fists primarch would have had no chance of victory.
