Whether you wait for the anime or read the book or manga is your choice. I personally prefer the book, which is why I don't stress about the anime so much - I'm more interested in whether someone will translate volume 14 or will we have to wait 5+ years for the official translation than whether the anime will get a continuation. If they do continue, I hope that they don't mess things up like they did with the first season.

And I'm not really that interested in rankings. Though most sites rate SAO's anime between 8 and 9, which is about right in my opinion. For character ratings and anime's ratings among other anime, you'll have to ask someone else who is more interested in such things.
