Yeah, he's in there, but by default.
In no particular order:
CM Punk
Chris Jericho
Rey Mysterio
John Cena
Batista
Triple H
Undertaker
AJ Styles
Then Randy Orton. I'm basing this on the overall quality of their matches by the way.
Taker and HHH I can see, but not the others. I have always found Batista and Cena to be redundant and boring in the ring. I don't mean they have limited movesets, I just don't find the way they execute their moves to be particularly convincing. CM Punk is on his way up, and may be the best heel in wrestling within the next year or so (if he's not already). But I just don't find him to be nearly as aggresive, nor as intimidating as Orton. I just don't think Punk is on Orton's level..yet.
Jericho is still really fun to watch, but he is slowing down. He doesn't have the speed and agility he once did, and it affects him in the ring. His character is becoming just a tad bit stale as well, but still very entertaining. Mysterio has worn on me throughout the years. I used to dig the whole underdog deal, but that's gotten stale. Also, I don't really like watching him in the ring with guys who could clearly stomp him out, no problem. Just not believable to me.
AJ is another guy who is on his way up, and is great in the ring, maybe better than Orton. But as a whole, I don't think he is anywhere near Orton, at least not right now. I like what he's doing with Flair, but he seems a bit green on the mic, and I'm not sure he's comfortable having an actual character yet.
But I'm totally biased. Orton is my favorite guy, has been since he came back from his broken collarbone. I think he made drastic improvements to every facet of his game after returning from that injury. I would like to see him involved in better, edgier, and more entertaining storylines, but I still think he's the best going right now.
