All Eyez On Me has the most highs as far as tracks that I still listen to to this day.

As far as overall quality it's probably WuTang Forever but I'm a west coast stan so All Eyez gets the nod from me just cause the album cuts like Heartz of Men, Scandalouz, Picture Me Rollin', Can't C Me, Wonda Why They Call U Bitch, etc. are all way more up my personal alley than anything on Forever or Life After Death, or anything else you listed.
