I like all sorts of different books on the SFF spectrum, and tend not to worry too much about classification.
A lot of nominally SF stuff has fantastical elements (psi powers, implausible technology, implausible aliens), and even hard SF has to handwave some details, so it's a spectrum rather than rigid classifications with bright lines.
That said I do think fantastical SF with explicit magic and other weirdness is a valid category and I do like it.
The setting matters a great deal. If the story is based in the far future, outer space, or on alien planets we tend to view it as SF, even with a large degree of magical involvement.
