Here's mine in order:

1. Aqua

2. Axel

3. Ventus

Edit: Somehow posted this in the wrong thread.

Riku
Axel
Those 2 I like the absolute best. As for number 3 that is really hard it's a tie between. Sora, Namine, and Roxas.

Aqua, Terra, and Ventus I like a lot too and pretty much equally to be contenders for 3rd place but I just like the other ones a bit more.

Here we go!

1- Roxas : Yeah he's probably my favorite character in Kingdom Hearts,
2- Sora : Sora has an optimism that really grows on you, and the love he has for ALL his friends is so strong it's hard to not like him.
3- Riku : Riku might be the most dynamic character in the entire game.

3.Terra

Hoping they all get some time in the spotlight in KH3.

Winnie the Pooh, Jack Skellington and Sora.

But I’m sure you meant original characters so I’ll go with Sora, Naminé and Riku, at the moment. I generally like every character in most Square Enix games.

1. Donald
2. Goofy
3. Sora

Side note: Goofy's success animations in the coliseum are the reason he reached that high in my eyes.

Xehanort
Xemnas

In no particular order, Xion, Roxas, and Axel. I know the game was a bit fanservicy in its story, but I liked 358/2 days and the richer character development it gave to someone besides Sora and Riku.

1.-Aqua - #SaveAqua
2.-Roxas
3.-Riku - Great character development

Both Aqua and Roxas deserve to get justice in KH3.
