Spoiler ShowI have long wanted to create this post
, but wanted to wait for the end of KH3.
I will not include Xehanort and Sora here, so in fact they are the strongest keyblade owners at the time of the end of KH3, before both died (Of course, Sora is controversial, but let's say he died at the moment)
This post is pure my subjective opinion I warn you.
1.Terra is controversial, but for me he is the strongest keyblade owner after Sora, he can transform his keyblade like Sora, plus he did well with Xehanort in BBS while Terra himself was on his feet and if not for the Xehanort plan to make Terra your ship, Terra would certainly be able to finish off Xehanort.
2.Roxas here is very controversial, I had been wondering for a long time whether the decision to put Roxas too high on the list was correct.
But given that Roxas nobody Sora he must be very strong. Back in 358/2 days, Roxas fought Saix, even when weakened, and then defeated Xion in its final form.
He won in a fight with Riku and if Riku had not turned on the "Ansem seaker of darkness mod"
Roxas would win.
Roxas can summon nobodies samurai army and possibly other nobodies as a whole. The ability to own two keyblade, because the lack of experience in the fight against the owner of two keyblade gives him a huge advantage over the enemies.
Well, in KH3 Roxas proved to be an excellent support.
I put it above Riku, just because he is more experienced and started to own keyblade before.
It can be seen that in his arsenal there are many strong spells, such as the same "Stopza", "Ultima".
4. Let Riku now not be able to use many dark spells as before, he is still a very capable fighter who can neutralize many powerful enemies.
Many people criticize her in KH3, but many people forget that she, being a warrior of light, was greatly weakened in the Kingdom of darkness, but I think at the best of times, Aqua is strong enough to defeat strong enemies.
6.Ventus, it is difficult to judge the strength of Ventus however the fact that he was one of the leaders of Dandelions suggests that he must be a very capable fighter.
But this is in the past. At the moment Ven is the most inexperienced of the trio TAV, but still quite strong, especially in the potential fighter.
7.Xion. In KH3, you can see that she can copy other people's attacks, like for example she copied the Saix berserk mode, after all this is a useful ability, well, her keyblade skills do not make her very weak, she was able to greatly weaken Axel in 358/2 days, despite the fact that she disconnected herself.
8.Lea / Axel, he is a good fighter by himself, but he is weak as a keyblade wielder, but this is not surprising considering that he has only recently become one and he simply lacks experience. But the ability to master fire in combination with his keyblade is potentially make him a capable fighter.
9.Kairi has nothing to say here, she is still quite inexperienced, given that she is just beginning.
At the moment, in my opinion, she is the weakest keyblade owner in the team.
All of the above is written exclusively my opinion, but I would like to know about your balance of power among the characters?
