Given that the stereo mixes have been remixed from the master tapes, one might assume/hope that they now capture the gestalt of the "proper" mono mixes. Given that Giles Martin did all this work (Giles is the son of George Martin, the original producer, who also did the manically cool work on 'Love' -- check out the NPR interview), one would expect him to have put the extra effort into the process to get it just so.

I think I'm with Peter. The stereo mixes must be the ones to get.
