Dragon Ball, simple as that. That is my fave anime series ever, and nothing can top that. I originally got into it by reading the manga at my schools library and soon I was hooked. It also completely got me into anime, so I thank DBZ for that. As of 2016, I have a helluva lot of merchandise, including all the manga, DVDs, shirts and even plushies. And to top that off, I recently did some drawings of my fave DBZ characters 
I have other favourites as well. Have enjoyed some slice-of-life ones like Gochuumon, Non Non Biyori, Kiniro Mosaic and Lucky Star. Pretty much had fun watching them, since it has a chillout feeling. Oh, and I really enjoyed watching Charlotte, which to me is like a mix of action and supernatural, with basically some comet giving you superpowers and having to combat others. It was really awesome 
I might watch some more anime soon, especially Samurai Champloo, since I listen to the soundtrack all the time. Could also give Fist of the North Star, Naruto and One Piece a try too, since I have the manga for them, and maybe some movies as well, like Ghost in the Shell
