Every example of "design by committee" can be matched by an example of a legendary writer's room (eg: golden era Simpsons)
Every brilliant auteur can be matched with an example of an "idea's man" who had to be reigned in by a team or was really a team all along with one person taking credit (eg: George Lucas).
I think it's more likely there are no hard rules for projects being better off with dedicated writers or teams of writers.
It's like asking if it's better for music to be written by singer-songwriter or a band working collaboratively. Both methods can produce great art.
But much like it exceptionally difficult to impossible to predict or manufacture a hit, I think it's probably a generally hard problem to determine what should be written by a team or a solo writer until after the work is already done.
