Both want the player to have the same kinds of experiences
compared to what? If that other part of "we" weren't Todd, it might be a good thing but since it is Todd, I don't think that comparison could be anything other than Oblivion.
Also, to have a better perspective on Emil, read his old editorials and reviews archived at Adrenaline Vault where he used to work. You can start here:

He may have changed for better or worse since then, but still it's important to know in my opinion.
As for why Emil became the lead designer, there's something funky with that. Is it possible that despite all the hype and glory, some of the suits might have sniffed some of the crap coming from Oblivion and Todd's leadership?
