Magical Mystery Tour often gets far more of a short straw that its individual songs might suggest it deserves.
If several of its songs had been on Sergeant Pepper that album would have been closer to the surrealism that many regard as one of the key components of The Beatles. Instead, Pepper seems of such lack of focus that is very easy to point to A Day in The Life if you had to pick 1 high point.
If Sergeant Pepper and Magical Mystery Tour were mixed in to a double album, it would be easier to say that was their equivalent of Brian Wilson's Smile.
Instead, it is possible to say that Revolver, Abbey Road and Magical Mystery Tour are better Beatles albums than Sergeant Pepper. Thanks to Drive my car and Norwegian Wood, It's not necessarily silly to say that Rubber Soul, is of a similar quality to Sergeant Pepper overall but that might be going too far. I think of Pepper as more like a hastily cobbled together (by their standards - great by any others) attempt than a collection of songs, or even a story, that you might necessarily get massively attached to as whole, A Day in the Life excepted.
But their most musically accomplished albums for me, that also give you a warm Beatles feeling, are Magical Mystery and Abbey Road.
I don't really regard The White Album and Let it Be as being albums. It's a few individuals throwing in their singles, art/rock pretensions and left overs with, of course, uneven results. At least on Abbey Road they genuinely jammed together.
