Which are the best SFW extensions for Tachiyomi?

I know this is not a Christian community, but I recently discovered Tachiyomi looking for alternatives to Saikou and a good alternative to read manga (which I don't do much, but it makes me curious) is Tachiyomi and although installing extensions is really simple the vast majority have NSFW content (or hentai?) and Jesus, I want to look for Pokemon manga and if I install extensions randomly I end up finding things I'd rather not have seen before, and many SFW extensions "don't work" or give an error that something went wrong.
