Hm... interesting questions.
I'm not big on overly-descriptive, overly wordy narrative. I prefer dialogue and action to move along the story. I can appreciate that some time needs to be spent on settings and back stories, but some authors go too far with it. For example, Nicholas Sparks spends pages and pages describing the small North Carolina towns that all of his books take place in, and it's a yawner to me LOL.
Most of my favorite books are written in third person. I don't mind first person, but I seem to gravitate toward third.
As far as specific authors...
I'm reading Stephen King right now, and sometimes I love his writing style, and other times it drives me nuts. Like when he goes off on these random, stream-of-conscious narratives that make you go WTF?? But he has a way of really unsettling you. It takes talent to come up with a whole novel about a rabid dog and make it good... Cujo was the first Stephen King book I ever read, and I loved it! And I cried at the end, for Cujo... he made me feel so much for that dog, even though it was rabid and attacking this poor mother and little boy LOL.
My favorite author is JK Rowling; I absolutely love her writing. It's quirky and cleverly funny, and she has the balance between description and action down pat. She can write scenes that are truly suspenseful and scary, and lines that make me laugh out loud no matter how many times I read them. And she's an excellent character-writer too; pretty much all of her characters are dynamic and interesting, from the good to the evil to the in-between.
