What anime would you recommend for someone who has only seen Cowboy Bebop and Attack on Titan?

I can't get him to watch anything else. He's not picky, just hasn't had the time. Mid-twenties, doesn't really know the anime world.<br><br>Saw this post and thought I'd ask the opposite. What anime do you think he'd enjoy and why? He's from Ireland, not sure if that matters.<br><br>Edit: he's not into subs but some of you are adamant that subs are better. That's fine, I understand. However, he is not going to watch subs. Recommend dubs or I'll ignore your comment.
