I have the early AND later 360 sound pressings of 'Time Out' and 'Time Further Out' and the 6-eyes easily trounce the 2-eyes for fidelity. How much of this is the 2-eye using a equed cutting dub I can't say. The character of the frequency extremes is truer and much more realistic on the 6-eye cuts.
You switch to the post-1970 recuts of these albums and they sound like they were recorded in a box. It's actually painful when you make this realization because it's difficult and expensive to buy only 6-eyes of every noteworthy Columbia release.
