If you talk about op==, then using fuzzy compare is a definite no-no, because it makes it impossible to define a hash function. Fuzzy comparision should be performed with a named function, qFuzzyCompare, and _only_ with that function. We need to fix other classes for Qt 6, too (e.g. Q(Size|Point|Line)F. That said, a qFuzzyCompare(QVariant, QVariant) would probably be useful, but requires extensive extra work, like hashing a QVariant, too.
