Apart from those 4 the best of the loyalists would, in my view, be Lion el'Jonson. The Lion never wavered in his support for the Emperor despite others doubts & mistrust of him & his own ambition. In fact when in a meeting with Curze early on in the heresy the Night Haunter told the Lion that he had forseen that el'Jonson would have his character tarnished by doubts over his loyalty well into the future, The Lion replied "loyalty is it's own reward.

On top of his loyalty Lion el'Jonson was lauded as the greatest general of all the primarchs, outstripping even Horus in strategy & battlefield tactics. His one great weakness was an inability relate well to the people about him & read them & thus found it difficult to trust or be trusted. Despite that his achievements were such that Guilliman once stated that Horus didn't take satisfaction in being chosen warmaster over Ferrus or Russ or Guilliman himself but found pride in being chosen over the Lion only. With little doubt, taking Sanguinious & his angelic charisma out of the equation, Lion el'Jonson was the greatest of the loyalist primarchs.
