I didn't receive my Ultimate edition yet (with all the DLCs), but I will have it in a few days hopefully! 
Yes I want to put Anora and hardened Alistair on the throne, and spare Loghain.
BUT I still think that the warden never abandonned Alistair, she never told him "I choose Loghain, so I want you to leave". No, the others from the team didn't like Loghain either, but still, they stayed until the end to help the warden fight the final fight. Alistair only saw his own grudge and couldn't see the big picture (Duncan was not killed by Loghain, but because a lot of reasons, Loghain is not the only one to blame but Alistair is too blind to see it), and Alistair prefered taking that choice personnaly instead of realizing that he was clearly abandonning the warden (his lover/best friend) just before a decisive battle.
He took her choice like a treason, but she could also take his choice like a treason as well (AND he is abandonning not only a friend but also his duties as a warden, Duncan wouldn't be happy about that).
So I'm not crying too much on Alistair leaving, to my eyes it is his own choice, no one asked him to flee from his duty and from his friends. He couldn't bear breathing the same air as someone he hated, while all the others from the group could bare it, at least until the final fight. Even if Loghain becomes a warden, it doesn't mean they have to work hand in hand until the rest of their days. I understand why Alistair would be angry and not wanting to work with a man he hates, but when he put eveything in the scale (do we say that?), his hate for Loghain outweighted all the rest: the warden's love, his duties, Duncan's will, the end of the Blight, his friends, everything. I would have expected him at least to come back at the last moment during the final fight, in order to help, regretting his impulsive choice of leaving at the Landsmeet, but no, he just went to some tavern to drown himself in alcohol.
With the retcon, drunk Alistair even became warden, while Loghain was warden as well, so it was totally possible to make both of them work as wardens. Too bad that Alistair realized it years afterwards.
(like this I know it sounds like I hate Alistair, but no, I really love him, it's just his last Landsmeet tantrum that I dislike, and his immature choice if we spare Loghain).
