Needs more tiers.
FIRST TIER
RZA (the producer, huge success & fame in TV / movies)
Method Man (most famous rapper, well known actor, the casual fan's favorite, the star)
Ghostface Killah (the most prolific, most consistent, most critically acclaimed, the rap fan's favorite)
ODB (if he was still alive. the Clan never recovered from his death. he rivaled Meth for fame and being the favorite, and was the most entertaining member, by far. The Wu albums post-ODB are missing that FUN element.)
SECOND TIER
Raekwon (has the most solo buzz in 2014, lot of high profile collaborations, not really a star though.)
GZA (most lyrically acclaimed, solid solos overall, but puts out material too infrequently)
Inspectah Deck (crucial MVP of some of Wu-Tang's most famous songs, but has a really shytty, boring solo career, unless you count the album with 7L & Esoteric)
THIRD TIER
Masta Killa (dope, had a couple nice solos, but come on, nobody cares.)
U-God (dope, had a resurgence with a couple nice solos, and some fire on 8 Diagrams, but come on, nobody cares, and he has wack moments)
FOURTH TIER
Cappadonna (I don't care if he taught Ghostface how to rap or whatever, he wasn't on 36 Chambers, therefore he doesn't count. It makes no sense to add him to make up for ODB - Cappa is redundant when you already have Rae and Ghost. If he HAS to be a member, fine, but he's going to have his own ranking on the bottom until he spits something amazing like he did that one time about twenty years ago.)
