Form of the dragon III Red vs. Gold

[Potato disciple]

So I was scrolling through some sorcerer spells and noticed in the Form of the dragon III entry that you gain

Quote:

immunity to one element (of the same type form of the dragon I grants resistance to)

The only difference(as far as resistances are concerned, at FotD I) between the Red and Gold dragon is that red gets resist fire 30 and cold vulnerability, while gold gets fire resist 20 and no vulnerabilty.

If both resistances turn to immunity at FotD III anyway, why pick Red (except fluff)?

Sometimes, fluff is enough. But other than fluff and some corner-case scenario, gold is better than red.
