FWIW stack uses cabal under the hood but is far easier to use. I would not use cabal these days, stack solves a lot of the dependency issues cabal had.

Yes, but not the cabal-the-binary. You don't need both installed.

For me, I use Stack personally, but I make sure that libraries can be built using either stack or cabal, by triggering CI with cabal.
