I liked both, but at different times.

When I first started out on guitar I really liked cobain. The reason is obvious, his stuff is easy to play. Once I started getting better I moved on to Alice in chains,and sound garden. There stuff was a little more complicated but was still a grungy feeling. Once I surpassed that I found hendrix. and once I could play any of his stuff I moved on again. And now I am were I am now, listening to dream theater.
