Nah, it makes you a completist. :) Everything makes sense except EYES WIDE SHUT. Why bother with the R1 version at all, unless you just want a censored version for completeness' sake? I just stuck with the Japanese R2 (it's cheap, and actually comes in a keepcase now)
I think that the R1 Eyes Wide Shut came with different music during the orgy scene. Because of the whole lawsuit against the original music Kubrick used. The R2 I've heard doesn't have the original music like the R1 does.
