To me this is not a hard ranking. For nearly a decade Austin has been producing high quality scenes, and if anything he's just gotten stronger. From his early days at Randy Blue he was a stand out, but he made the wise career move to branch out to major studios and perhaps the wisest move to dive into his own site: 4myfans. Austin is actually #1 on Porn hub currently, so I'm not alone in giving him this title.
Aside from his obvious physical stature, he's a good actor, has a surprisingly kind voice (unless he's trying to be menacing) and can fuck like...well, a porn star. He seems to enjoy his work, especially when he goes into ecstasy during nipple play. To see such a big guy freak out like that is beyond hot. There used to be a compilation of his orgasm clips floating around that was amazing, but i guess is violated tons of laws so its gone.
If I were younger and bitchier I would get into some of his tattoos, but if I looked like him I might get my stage name on my back too (it probably has another significance, but I know its not his real name). And I also have tons of forearm tattoos, so can hardly cast a stone here. It works on him.
In any case, he is stunning to watch, and a beautiful man. I saw him in person once and can say it's not smoke and mirrors--he's hot.
And just to top it off, he seems to be a stand up guy. He recently had a troll battle with the internet because he did a scene with a Misael Diaz, a feminine appearing dominican model. Let's just say that Austin was the good one, and the internet at large sucks.
Austin, keep doing what you are doing and as you say "love your fucking job".
