Life Is Good
The Lost Tapes
Depending on what version you have I Am. The rest are toss ups and/or personal taste except for Nastradamus which was basura.
If NaS isn't one of your fav rappers of course one would say his albums don't have great replay value despite the fact that they do. It's all subjective, I don't know why you'd ask that question like many would agree if they're actually fans of his music.
IMO It Was Written has the best replay value. And that IMO is his second best album behind Illmatic
