Pink Floyd The Wall--Which vinyl?

I have the opportunity to purchase early 80's Japanese vinyl in NM vinyl and Ex cover for about $40. I see that there is a new Capitol remaster for about $44. The new remaster has mixed reviews at Acoustic Sounds but some say it is better than the 80's Japanese and CBS (I think half speed).

Has anyone compared the two? I guess I could by both to compare and maybe sell the loser but I would rather not.
