I don't think you can compare Aces and Eights with these groups, they were the main guys for months. That and the fact that they have total lameos is why they're worse.
But you can have total lameos and still be presented as a strong faction. Proportionately speaking, the nWo probably had a similar big-star to non-star ratio, and they were badass before they petered out also. I'm not saying A&E is great or anything, but to say they're the worst? When the Oddities or Los Boriquas or pre-revamped Nation of Domination with Savio, Crush, and PG13 are right there?
No, far from it. A&E was booked pretty well for awhile, a miracle considering TNA and all, and like anything in TNA they just went to shit.
