I've tried a bunch of alternative prelude and my experience is that it makes it very hard to integrate with code that uses the standard prelude. Foundation seems to have the highest chances of success right now, ClassyPrelude seems to be the most well-used, and Protolude seems to be more like a framework to build your own prelude.

I've never understood the hard-to-integrate argument; I can still do `import qualified Prelude as P`.

Right, but you need to do explicit conversions between `Foundation.String` and `Prelude.String` at your app's boundaries (for example.)
