I've played around a bit with "classy-prelude", but recently I stumbled into "definitive-base", on hackage here - https://hackage.haskell.org/package/definitive-base. 

The documentation is sparse, but there's some brief information here:

https://marc.coiffier.net/projects/definitive-framework.html

It looks interesting, but I was wondering if anyone has used it as a replacement prelude, and perhaps written/blogged on it? I'm just looking for a bit of a primer I guess.
