My Haskell experience on NixOS is wonderful!

I think it depends on your district. On some distros (looking at you arch!) I think GHCup and keeping things in /home and out of your system package manager is the better approach.

That said, I never had issues with Pandoc on any distribution. But I have struggled with Pandoc extensions, before I got NixOS (and flakes).
