From what I understand, fan translations can often be more "direct translations" of names. Though, Viz Media and Crunchyroll are going to be official translations that the wider community is going to recognize faster.

With that in mind, I would lean towards official names but if you prefer a more accurate translation without Western toning, then fan translations aren't exactly wrong but may cause some more confusion down the road. SEO wise, I would go with what is official by Viz or Crunchyroll.
