As far as I know, neoEverett is the smallest realist interpretation: Eliezer argued not only against anti-realism, but also in favor of the smallest theory that falls out of the formalism.
But MWi looks huge compared to RQM: it reifies basis, which is much more naturally explained as a choice by an observer, ie a "map" feature.
There are a number of kinds and grades of non-realism. Objective collapse theories reify both state and collapse,
MWI refies state only and RQM refies neither. Nonethless, it is not a completely anti-realist theory.

As far as I know, RQM is not even a complete interpretation of quantum mechanics. In the original paper by Rovelli, there are many holes left which I thought nobody has patched yet. If you know of an exposition that corrects those problems, I would gladly read it.

You have to value elegance more than correctedness, though.
I'm not say that RQM is incorrect, but I am saying that until it's completed, nobody can tell if it's correct.
Also, nobody can guarantee that when completed it won't carry more weight than neoEverett.
I'm not putting g a 100%..sorry, 99,99999% weighting on RQM. But its very existence undermines EYs argument for MWI,because it suggests third alternatives to a number of alleged either/or dichotomies

An incomplete interpretation that is in the right lines may be better than a complete one that is not.
