You could do a search of the forums as this has been asked many times, IMHO:
1) Japanese "Pro-Use" half speed.
2) Mobile Fidelity UHQR half speed
3) German first pressing (almost a tie with the UHQR but with very different strengths and weaknesses).
4) British Harvest First pressing.
Skip all US pressings including the horrible regular Mobile Fidelity, ditto the standard Japanese release.
