i'd get the american reissue trem. they are identical to the vintage ones. the japanese ones have the string spacing closer together, the hole for the collet looks too big, spring is not as strong, trem lock button hasn't got swirl marks on it, trem doesn't clip in like american one, stainless steel instead of chrome plate like the american one, logo is different, screws aren't nickel plated, and they just generally look cheap. since the american one is only $10 more than the japanese one, get that:
