I picked Mobb Deep btw, even though Prodigy is my favorite rapper of everyone in these groups, and The Infamous is my second favorite album of all released from the 4 groups (Death Certificate being number 1). However, he's not that much my favorite over the others and Infamous to me isn't SO much better than the other albums, that it makes up for how much we'd lose if I take away the other three.
If we take away Mobb Deep: We lose 2 classic albums, 2 other dope albums, Havoc's production, Prodigy's A+ rhymes
But if we lose NWA: We lose Dre, Cube, Death Row, Bone Thugs, Friday, Snoop Dogg, The Chronic, Doggystyle, Amerikkka's Most, Death Certificate, etc...just too much
We lose Wu: No Only Built, Ironman, 36 Chambers, Supreme Clientele, Liquid Swordz, and a bunch of other great projects, RZA production, all the amazing guest appearances, etc...
We lose Gangstarr: We lose 3 classic albums, 2 other really great ones, No Sun Rises in the East, and none of all the amazing beats Primo did. No NY State of Mind 1 and 2, no Memory Lane, no Unbelievable, No Dwyck, none of the Group Home production, So Ghetto, D'Evils, Kick in the Door, 10 Crack Commandments, etc....
