PVA mortar is great, but the only thing you can't do with it is feather
it really thin, because you're limited by the sand grain size. Cement
based self levelling uses much finer dust than soft sand, so allows you
to feather it down to almost nothing.

I don't think the self-levelling stuff is cement based. Cement coloured
certainly, but some strange kind of mineral that IIRC doesn't set without
the latex binder.
