  We introduce and study the family of uniformly super McDuff II$_1$ factors.
This family is shown to be closed under elementary equivalence and also
coincides with the family of II$_1$ factors with the Brown property introduced
in arXiv:2004.02293. We show that a certain family of existentially closed
factors, the so-called infinitely generic factors, are uniformly super McDuff,
thereby improving a recent result of arXiv:2205.07442. We also show that Popa's
family of strongly McDuff II$_1$ factors are uniformly super McDuff. Lastly, we
investigate when finitely generic II$_1$ factors are uniformly super McDuff.
