ovoon: I'd recommend the Berserk manga over the show. It's significantly better in just about every way. The story is 300x longer, the art is so good that it would be really tough to animate, and the atmosphere wasn't captured nearly as well in the show. Also, the show isn't as gritty. And Berserk is the grittiest thing I've ever read.
Well yes I agree with that (same goes for Trigun, but it stil handled itself better than most adaptations in regards to original material especially considering there were only 2-3 volumes out at the time), but I was naming popular or common choices among what could be considered entry level anime.
Not to mention that the manga would be a significant investment in time and money (especially with it only being about 2/3ds to 3/4ths the way done with the recent end of the Millennium Falcon saga and only about a volume or so coming out each year) and some people aren't really willing to make that investment.
