Okay when I was a kid..Wu dropped Enter the 36 Chambers and cats was on it. C.R.E.A.M. was everywhere but for the longest time it was the only Wu- song I heard, some people listed to Proteck Ya Neck and Mystery of Chessboxing. Cats didn't really rock with the Fugees that much, they were way too conscious. However BONE? Shit I heard that shit everywhere. When Creepin Up On Ah Come Up dropped No Surrender & Thuggish Ruggish Bone was fish grease in the hood.
Now for my personal opinion I pick Bone as a collective. My reasoning is if you look at Bone's work they had Creepin (1994), E.1999 (1995) and Art Of War in (1997) and that's not mentioning the amount of singles they dropped, they clearly dominated as the group of the 90s.
Wu as a collective disappeared for a few years after Enter The 36 Chambers. There was a massive amount of critically acclaimed solo material but we are talking groups right, so I'm guessing we should be discussing group albums. They only had 2 albums in the whole 10 year span.
The Fugees, rather Lauryn Hill, made a big impact and the crew was strong. I definitely feel The Score is one of the best hip hop albums of the decade. However they only had the one great album.
Hell, Naughty By Nature should be mentioned more than The Fugees for that reason alone.
And to add to this: Bone was a much hated on group during the 90s. 3-6 Mafia, Twista, Do or Die, Crucial Conflict, Psychodrama, Dogg Pound all took shots at them. That type of shit only happens when you on top.
They were also a beloved group too, they did tracks with some of the hottest rap acts of the 90s: Master P, Biggie, 2Pac, and of course Eazy-E. They were literally well represented all across the country.
