Fëanor's Death, Convenient?

[Maédhros]

Then he died; but he had neither burial nor tomb, for so fiery was his spirit that as it sped his body fell to ash, and was borne away like smoke; and his likeness has never again appeared in Arda, neither has his spirit left the halls of Mandos. Thus ended the mightiest of the Noldor, of whose deeds came both their greatest renown and their most grievous woe.

Do you think that his death was better for the Noldor in general because it allowed for the healing of the houses of Fëanor and Fingolfin by the actions of Fingon and Maedhros?
Or the might of Fëanor would have helped the Noldor further against their war with Morgoth? Remember, Fëanor would have not accepted well the position of Thingol as the Ruler of Beleriand as Fingolfin did.

Thirdly: because after the death of Fëanor the overlordship of the Exiles (as shall be recounted) passed to Fingolfin, and he being of other mood than Fëanor acknowledged the high-kingship of Thingol and Menegroth, being indeed greatly in awe of that king, mightiest of the Eldar save Fëanor only, and of Melian no less.
