To me protestantism in general is bad, of course there's groups that further align with Catholicism but ultimately all of them either have no hierarchy, barely a hierarchy and/or an invalid priesthood, which is an issue and makes reunion with Catholics impossible unless they abandon protestantism entirely. I don't see the East-West schism as something that had to happen, it could have been avoided and unlike the schism with the protestants, the East wasn't proposing heresies, it was highly influenced by both misunderstandings and competing over the Christianization of the Slavs and ultimately was a huge tragedy.
