Well I agree with all your defenses of Auron. Don't care that he didn't reveal everything and don't care that he's kinda cliche, because I always say what you said in the write-up there. Cliches are cliches for a reason, and there's nothing wrong with a well executed cliche.
That being said, I've never been super huge on him. Not cause I have any particular problems with him just cause... eh. He's not as badass as people think he is. He breaks his stoicness too much to be a stone cold badass, but is too stoic to be that interesting. I know you were saying his rare moments of compassion and stuff make the character appealing to you-- probably make him less so to me. If you go the strong silent type (a type I'm iffy on in the first place) you really gotta go all in with it (see Sol Badguy), generally, to sell me. Or if you're going to break your stone cold appearance, you've gotta do it more than just a little like Auron does (see Vash the Stampede). Least that's how I see it.
Bonus Question: Who is your favorite Final Fantasy X character?
I'll do you one better, cause everyone loves inequalities. (also since you probably know my top 1, maybe 1-3, anyway)
Tidus > Seymour > Rikku >> Wakka > Jecht > Auron > Yuna (> Leblanc lol) >> Lulu >> Kimahri
