I'd take the iFixit recommendation with a sack of salt. Their business model relies on being able to sell components and tools that can open up laptops. With the new Retina MBP, they can not do much, hence they are bound to rate it lower.
Apple's task is to create a laptop with the features they think users will like, and not have to worry about the support for third party component vendors. If you think iFixit is your source for recommendation, don't buy the MBP. :)
