Congrats on the newborn.
Lloyd Chambers has a very emotional connection to Zeiss lenses. Anything that isn't Zeiss is no good as far as he is concerned.
He is also not a photographer.
Try Photozone for non-biased lens reviews/comparisons.
Also, the Nikon live view implementation is something that gets a fair amount of flak (ref: DPR and FM's 5D Mark III/D800 field report). Something about interlacing? The Canon Live View implementation seems to get the kudos all round.
I have also been very impressed by the contrast detect focus on my 5D Mark III; focusing in ISO-12,800-16,000, f/2.8 light (dimly-lit wedding reception) not being a problem at all. It is nuts!
