The Shield or the Nexus?

For me I believe that the nexus is the better faction because they had a rivalry against pretty much the whole company, leading to an elimination 7-on-7 tag match at Summerslam 2010 which is the best match at Summerslam for years. Wade Barrett also had a WWE Championship push in late 2010. When Wade Barrett did not win the championship, I did not like it as it would have given the Nexus a final dominance.
Now the Nexus is like this
Wade Barrett - Injured but multiple Intercontinental championships.
Daniel Bryan - Injured but multiple time WWE World Heavyweight champion.
Heath Slater - 3MB and humiliated but funny.
David Otunga - A movie holding flask of coffee and nothing else.
Skip Sheffield - Repackaged as Ryback after injury, title push now part of Rybaxel.
Michael Tarver - Left WWE
Justin Gabriel - Grew his hair and NXT sometimes.
Darren Young - Prime Time Players and came out - Very Courageous.

My rankings in 2010 in terms of impact and success.
1.Wade Barrett
2.Justin Gabriel, Heath Slater, Daniel Bryan, Skip Sheffield, Michael Tarver, Daid Otunga, Darren Young

My rankings in 2014 in terms of impact and success.
1.Daniel Bryan
2.Wade Barrett
3.Ryback
4.Heath Slater
5.Darren Young
6.Justin Gabriel
7.David Otunga
8.Michael Tarver

The Shield did not obtain my vote because they done a face turn when the should of stayed heel. Roman Reigns was the one who should have turned face to leave Seth Rollins and Dean Ambrose on their own.

ps Wade Barrett,Heath Slater and Justin Gabriel were joined by Ezekiel Jackson to form the Corre on Smackdown with not as much impact.

pps 8 is better than 3.

Thanks for reading.
