The issue with anime seems to be that...
There are a lot of great shows but it seems like one or two shows just act like a vacuum and just dominate .
Meaning any show that has broken outside of Japan is the show that gets the focus the most.
I think Attack on Titan is the show now but even a show like DBZ are still insanely popular then many current anime shows. Maybe not in the anime fanbase but clearly in the overall audiences.
