The presence of Seth automatically invalidates that claim. But for shyts and giggles what's the argument the Shield is better than NWO, Evolution, or the Four Horsemen?
How does the presence of Seth invalidate that? He's a good wrestler and has a good character. He's finally hit his stride because this annoying dikk head persona seems like its him in real life and....oooooooooooOOOOOOOOOOooooooooooOOOOOOOO

don't disrespect the gawd
NWO was revolutionary but at a certain point the actual group became trash. The Sheild never added new members much less 100 of them... and Hogan was stinking it up all up in the videos...the lows balance out the highs.
As for the four horsemen... once again they never had to add new members to stay fresh. And everyone in the sheild went on to become a star... four horsemen were a bunch of lackeys to Rick flair.
Evolution created stars but was a horsemen rip off and trips was wilding with the reign of terror... also when Evolution came back to face the sheild we saw what was up.
SHEILD had no defacto leader therefore there were no lackeys. All of the members were equal even when Ambrose was singles champ and Reigns and Rollins was tag. Dirty Dean never came off as the big cheese.
Every member has also been World champion. Evolution did that too but Sheild is way better
