Possibly the top moment of 2010 was the debut of the Nexus following the end of NXT Season 1, and the compelling storyline that has followed. And while the feud with John Cena fizzled out after SummerSlam due to questionable booking, these three core members will continue to make an impact for awhile.
Gabriel is very similar to AJ Styles, in that he has amazing in-ring ability both on the mat and in the air, but lacks mic skills.
His 450 splash is one of the best executed top-rope finishers I have seen in a long time, with unmatched precision and crispness. He may very well have the in ring ability to be a major player for a long time despite his poor charisma.
Otunga is the opposite of Gabriel. He is very limited in the ring, but has the size, look, charisma and mic skills to be a major player in WWE. On top of that, being married to a Academy Award and Grammy winner works well to his advantage.
But it's Barrett who's the star of the group. He possesses both the in-ring ability and charisma to be a main eventer for a long time, having already main evented a couple pay per views in his first year in WWE. While he hasn't won a title yet, expect that to change really soon.
