Kenta is probably the closest to his level with Steen. But Bryan is just ahead of both of them in my opinion. Steen is awesome but unfortunately his weight does limit some of his abilities, though he's fantastic for his weight size. But with that weight you lose the speed and agility that Bryan for example has. Bryan is also just as technically gifted as Kenta, but he just executed it in a better way - his psychology is better, so I agree with Crayo that Bryan is the BITW.
Though people right Punk off a lot recently. Sure, he's not the best in the world, but he's damn good. His matches with Jericho & now Bryan are proof of that.
Ziggler isn't as good as Punk technically. He's a better seller, he's on Bryan's level with selling, but Punk is a better technical wrestler atm. Ziggler has loads of time to improve though.
