Is Earthly or GNU Emacs better?

Neither clearly leads. Earthly starts at Free and GNU Emacs at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Earthly or GNU Emacs?

Earthly starts at Free and GNU Emacs at Free.

Does Earthly or GNU Emacs run on more platforms?
