I don’t know which to watch first or not, but like budonoseito said, don’t burnout yourself. Dont watch something just for watching it because its on your list or whatever…watch what you want to.
If it’s to complement your japanese learning, try to go with easier ones. But look out for the comedy, I try to watch Gintama and it is FULL of puns and wordplay, so I dropped it to watch it when i’m better.
Also, what I like to do is watch a anime with a story and another with indivdual stories(episodic). So if during a week I don’t have much time I’ll just watch the episodic one and if I have all evening on another night I’ll play multiples episodes of the other one.
