Mostly film ones like Empire, Total Film, Hotdog or DVD Review, sometimes I get the PC ones just for the free software on the discs, and rarely I get 'lads' ones like Nuts or Zoo.
I used to read the Beano and Dandy and such when I was younger, but I've never really liked 'proper' comics (prsesuming you mean more like graphic novels)
Not sure I have a favourite because I haven't read a wide range of things. Timothy Zahn wrote a really good Star Wars trilogy, Kevin J. Anderson has done a few X-Files and Star Wars ones that I liked, perhaps Dan Brown too, though I haven't read many books by any of these people.
I like the Da Vinci Code, but I don't thing Dan Brown is that good. One of my favourite writers ever is Gabriel Garcia Marquez. I find something enchanting in the way he writes.
