Mine would probably have to be Attack on Titan. It's only rated 8.5/10 on MAL but it's #2 in Popularity.This is one of the first anime I have ever seen and it has had a lot of impact on me. The first season and the music in it is what I loved most about it.
Berserk. It's my #1 favorite and probably always will be. I never actually read manga, I just watch the anime... And they're now making new episodes and will hopefully follow the manga until it ends. It's the only anime that I enjoyed enough to read the manga, and I've read up to the millinium falcon arc twice now, but sadly have fell behind and haven't read it in quite some time -something I need to do.
The movies are better than the 90s anime and tells the same story, but the movies are closer to the manga and introduces characters who appear in the 2016 anime who weren't in the 90s anime.
I believe it was said that the 3rd movie is the goriest anime ever created? At least that's what one of the reviews said when it first came out.
I've watched 200+ anime's (Why I'm a weeblord). And one of my favorite anime's is One Piece. Reason why is, every time I watch this show I always get excited and pumped when Luffy hits the fan, and this show has over 700 episodes, and seeing how this show still gets me pumped AF is why its one of my favorite anime's.
