If you're competent with Haskell, don't bother. A new Prelude will save you a bunch of imports; that's it. If you're fretting over which one to use, you've already spent too much time making this decision; just stick with the regular Prelude and use your imports.

The worst thing about the default Prelude is that it encourages bad behavior among new users--for instance, with partial functions like `head`. Experienced people know what to avoid and what to work around. So if picking an alternative Prelude seems like too much work, it is.

I have a project where I have mostly dumped the Prelude. All it is doing is saving me a bunch of imports. That's nice but not earth-shaking.
