TAV or SRK?

Hard to say.

If you just went by how each group accomplished, Sora, Riku and Kairi would appear to be more powerful.

But Terra, Aqua and Ven were blind sided early on. A remnant of Terra was the hardest boss of KH2FM, Aqua beat Xehanort and has survived in The Realm of Darkness for years.

So, I'd have to go with even.

TAV! They are more experienced.

TAV.

 

They don't need a second keyblade.

They aren't awesome enough to wield two keyblades.

Terra, Aqua, Ventus for experience.... but for long career... Sora, Riku and soon Kairi as well

Sora saved the world twice. Riku assisted twice. They've blocked Xehanort three times between them. And Kairi.... helped.

 

Terra and Aqua both failed at nearly every task they were given, and both abetted to the continuing problems and near world-ending that has occurred during the series. Ven's actually the only one who managed to do what he set out to do (become a hero worthy of hanging around his friends).

 

I'm going with Team Sora.

Dave's got it right.

To be fair though, Terra was just really gullible and aided the villains, and Aqua saved Terranort because it looked like Terra could've broken Xehanort's hold over him, she didn't think he'd lose anyway. But yes, Ven is the only one who managed to accomplish his goal, and stopped Xehanort to a certain degree by destroying the X-Blade, oh the irony. The more experienced wielders failed to do what they set out to accomplish, and the rookie keyblade wielder accomplished what he needed to do and then some. Same goes for Sora, since he didn't really train to become an experienced Keyblade wielder until DDD, before that he was completely self taught.

My personal favorite trio is TAV but if you want to go on success rate, it's clearly SRK.

TVA. SRK are the main characters, so they defy logic.

Axel, Roxas, Xion for the win!!!

 

Okay, just kidding. In reality I have to go with TAV. I know that SRK are more accomplished, but TAV had no idea who was the bad guy until the end. All they knew is that the unversed were evil creatures of darkness. SRK knew that the forms of Xehanort (Ansem SoD, Xemnas, YMX, etc.) were the bad guys all along. If TAV knew that Master Xehanort was the bad guy, they would have easily blown him away, but Master Xehanort was smart and did not give off his plans. He manipulated Terra in thinking Eraqus was bad, but after that was when they figured out it was Master Xehanort who was evil. So TAV had an unfair advantage. But if they come back in KH3, then they will definitely IMO be much stronger than SRK.
