They're not better than any of those, nor have the mainstream/pop culture appeal of probably 9 of those on that list. People reference nearly every one of those to this day. There's probably others I could add through personal preference (Brood, RTC, Jersey Triad), but I don't think they had the group nor solo impact that Shield had. It's not even a slight to the Shield, it's just that there were a ton of stables that did far more before them and all these years later still resonate with current and former wrestling fans. 10+ years from now, Shield will be talked highly of cause the WWE has practically had a mandate to beat the Shield's legacy into the viewers' heads.
