Which manga do you recommend me to buy?

Ja
5

Today I plan to go to the manga shop near me, but the question arises whether I should buy the second part of Eden's Zero or any Jojo part, the problem with Jojo is I can do Part 1-5 on Crunchy Roll and watch parts 1-3 on Netflix I doubt they even have parts 6-8 at all.

Is a very good manga with a great story and a lot better than the anime.

Parts 5-8 are only available in Japanese and French and believe in Italian too. Part 1-4 is available in English. From next year the manga will be translated into German so I would still wait.
