Here's the thing, and probably the good part about Sting/Taker not happening
.Sting needs to go over. This isn't a passing of the torch, this is likely his singular moment in WWE, so it needs to be big and he needs to win.
Of the people you listed
1- Triple H- this is probably the most likely scenario honestly, as even though I'm of the Bret Hart philosophy about the guy, he considers himself a legend, and he would put Sting over.
2- John Cena- not gonna happen, unless Sting wrestles several matches and retires with Cena. Sting is the ultimate baby face, and Cena doesn't do the honors very often, he only trades W/Ls, case in point Rock and Lesnar, he's 1/1 with both of them. He let himself look equal but never inferior.
3- Randy Orton- too low on the card, not interesting enough of a feud. He would let Sting go over, but thats about his only value here.
4- Batista- pointless, we'll be lucky if he comes back for a few months if that, and then he's gone again. He isn't important enough for the feud to happen.
5- Bray Wyatt- this has potential to be a fun feud, but Wyatt's character has lost a ton of momentum because of all the losses suffered, and if he faced Sting he'd be adding another L to that list.
6- The Rock- see Batista.
7- Brock Lesnar- the ONLY way this could happen (and honestly it would be ridiculous, but fun nonetheless) would be if for the next 5 months Brock runs through the WWE, Sting is a surprise entrant and wins the Rumble, then does his staring from the rafters bit, and basically repeats WCW 1997, where's he's WWE's only hope to stop the monster. Then he would beat him for the title at WM, of course this begs the question where do you go from there?
8- Kane- never gonna happen. Same situation as Orton, but even worse.
9- Chris Jericho- similar to Batista and Rock, plus who's the heel? Jericho could obviously work a great match with him, but I don't think there's enough appeal there, Jericho hasn't been built up that way this run.
10- Daniel Bryan- hopefully, Bryan recovers 100% and has several good years left, but I'm kind of doubting that at this point. I think they could work a good match, but I'm just not seeing the story, at this point Bryan is way too sympathetic of a character to ever be a heel, and Sting will be way too over to work heel. I just don't see it happening.
So of these 10, your answer (whether I like it or not) is Triple H.
