They also had writers who favored Angel over Spike. Fury and DeKnight fought over who should win the battle in Destiny.

You can almost tell where each writer fell on the commentaries. Except Whedon.
I could never tell with Whedon most of the time. With one or two possible exceptions (which may have been actor related), he was very good at keeping his views close to his chest.

Although he did come forward in an interview recently and list the characters he preferred and the one's he didn't, which sort of explains Angel the Series and his odd relationship with Greenwalt.
