I should be ecstatic, but I'm not a fan of most of the changes they've made.
First, the method of transforming in GT, which required going ape-mode first, was a lot better narratively than Old Man Power-up.
Design-wise, the old black hair colour contrasted with the reddish fur better (which is why it's the one time I don't prefer Gogeta's design over Goku's), and I don't like how the fur stops mid-way down the forearms instead of at the wrists. But it's actually a good change that it doesn't automatically/temporarily make Goku an adult again.
