I haven't seen the anime, but the manga is top notch. Currently the manga is on hiatus so no new chapters since sometime in May. I consider it better than Naruto as the system in Hunter x Hunter is a lot better and more indepth than the chakra system. Not to mention the story line is pretty good for Hunter x Hunter.
If you have the time I recommend reading it, you wont regret it. Just don't bother with the anime. The anime hasn't been done since around 2002 I think and it stopped in the middle of an arc. I doubt, considering the length of time since, that the anime will pick up again.
Yup, favourite character is Kakashi. He's just hilarious with his granny jokes and his book . Close second would be Shikamaru. Very intelligent, yet very lazy. His views on woman are very comedic. Who's your favourite?
Naruto is my favourite anime though. What's yours?
