He does get a lot of flack for X though.
Well everyone except maybe Auron gets flack for their voices in that game. I am of the opinion that the voice-acting isn't nearly as bad as some say.
In fact the only truly bad voices in the game are maybe Kimahri and....well, Kimahri.

As well as the Dissidia cast. Kuja's VA said in an interview that the direction was awful and they were given very little to work with.
Yeah when I beat FFXII and found out Gabranth was in Dissidia, I quickly looked for stuff of his on YouTube. To my great surprise, one of the best and most awesome voices from XII suddenly sounded like absolute garbage.

Dissidia's voices were a disappointment in general.

And yes, VIII's cast is rather pathetic, I have to agree.
Laguna was a way cooler hero than Squall. Fact.

Well, my opinion. But still... Fact.
