As someone who reads fantasy fiction a lot, honestly I'd prefer if I read everything in American English. The biggest thing that gets me is e.g. "defence" instead of "defense" and other places where British English uses a 'c' instead of an 's'. It seriously diminishes the immersion for me, even if I've read probably 50+ books with the version I'm not used to by now.
It's never stopped me from reading a book before, but it does diminish my enjoyment quite a bit. For nonfiction, I don't care, I'm reading actively regardless. But when reading passively for enjoyment, it's noticeable and irritating.
