Growing up, I was a HUGE Beatles fan. I tried to pick up pressing from all over the world. Having said this, I have a few of those Japanese Odeon albums and I think they sound better than most of the other Beatles' vinyl I have. Of course, I don't have the Mobile Fidelity set, which probably sounds the best.
Have you checked the Steve Hoffman forum? I'd do a search of their board, I bet they have covered this already.
