Vintage vinyl or new reissues?

Can someone comment on this subject. Preferably someone who has compared the old with new reissues. For example would a new sealed bob dylan highway 61 revisted, released by columbia always sound better than good reissues? How does one approach this question?
In the context that both the records are clean, mold, warp and scratch free and in like new condition. This thread is not about price but about which, if executed properly, will deliver the best SONIC results. Thanks.
