Hey Erick,
So it's tricky for me to answer your question definitively, but it's worth highlighting that both Moz metrics and Majestic metrics are simply there as a guide to relative page strength. Weak pages on strong domains frequently outrank stronger pages on weaker domains if that makes sense.
Additionally, Google take many factors into account when ranking pages - not just links. As I mentioned above, from a user's perspective that page is a 'good result' for reviews; hence Google tend to rank pages like that well. As such I suspect you may struggle to outrank the page.
If I were you, I wouldn't reach out to the blogger to ask them to delete the link. The danger is that (as you said) you start a whole new firestorm and attract a bunch more links to the ROR page. I suspect it's not that link that's making a difference in any case, so even if you did get it removed, it's likely that the page will still rank.
Cheers
Hannah
