Batoto is almost always best for official scanlations, and they support the scanlators. If it's not available on there, I turn to third party sites. Kissmanga I'd preferable to me because one chapter is available per page, and you can scroll through all of them with relative ease.

I tried to read Fairy Tail on Batoto when I first got into it and some of the stuff the translated to just didn't feel right. Transferred to MangaFox and continued and it just felt more real and authentic. I think it comes down to personal preference and what you think the characters would actually say in a certain case.
