DBZ is one of my favourites! I still watch the reruns sometimes.
I saw Gundam Wing, which I really loved. I didn't see Gundam SEED. I still plan to watch Naruto, Bleach, and One Piece (amongst others). Attack on Titan is great! Another moderator (Delta) told me about it a long time ago and I think I finished watching it in 2 days. It's a great anime and I can't wait for the next anime season. I'm tempted to read the manga, but I generally prefer anime.
I used to be a huge Pokémon anime fan too, but my hype for that has dropped significantly. I still keep up by reading summaries and watch episodes when something exciting seemed to have happened. I do plan on having a marathon to watch everything I haven't seen yet sometime.
My current personal favourite is Fairy Tail. People say it's similar to One Piece (I haven't seen it yet). I really love the battles, the humour, and emotion in the series.
Edit: I also just saw you're from Europe. Which country are you from? I'm from the Netherands.
