Re: Avatar (James Cameron)
I don't think there is a top of the hill. I think plenty of us pretend there is...but there isn't

ILM is technically superior to WETA, but ILM has one real scene of a CG character emoting (Yoda in ROTS...awesome work), whereas WETA has a longer and more varied track record of getting "performances" from fully CG characters. I was surprised at the announcement because of Cameron's experience with ILM. But in retrospect, WETA's resume is more in line with what Avatar needs (the major emotional investment, the acting).
I think both have near flawless reputations. Cameron might have picked WETA because he really responded to LOTR, or because PJ begged him, or because of my speculation in the previous paragraph

It's not like ILM is crying, looking for work.
But when it comes to effects and directors...Cameron is *THE* guy. More than Lucas, Jackson, or even Spielberg, he'll squeeze the effects team like they've NEVER been squeezed

WETA will have to hit new highs for him. Not just new highs for WETA...but totally new high points. That's working on a Jim Cameron film.
