As a fan of Nentir Vale I think that Wildemount out PoLands the Vale. It's a classic style setting tinged with darkness. People comparing it to FR I am unsure if they have read an FR book or the Wildemount book but there are a lot of differences and more than just cosmetic. Maybe Tal'dorei as a FR like setting but Wildemount has its own identity. Many aspects seem more eastern European than the FR's Western European bent which is actually pretty significant as the East & West were markedly different. It has a pre-Renaissance feel, right on the cusp, with the Dwendalian Empire reminiscent of the Holy Roman Empire. The Kryn Dynasty also feels very unique, nothing really comparing to an Earth culture and the approach is very cool with the Beacons and reincarnation ideas. The Menagerie Coast is very Caribbean vs FR's Sea of Fallen Stars which seems more Mediterranean if I recall correctly. The approaches to races and cultures is fascinating as well. The Kryn Dynasty is ruled by Drow, sure sure but they aren't our typical Drow but they are and how they handled that is inspired.
What's really cool is that the integration of classic D&D tropes, like Vecna and the other GH deities from the Dawn War pantheon, isn't jacked. Mercer approaches it in a very organic way and the cults are handled in interesting ways as well with Warlock Patronage and Clerical domains.
All this adds up to it not feeling like a kitchen sink FR style D&D setting.
