with visudo.

Here is my recommendation.

export EDITOR=/your/favorite/editor
sudo visudo

that will change the editor that visudo uses to your favorite editor.

Maybe someone with the exact distribution that you have can give a
recommendation for an exact path to an easy to use editor.

if you are just puttering around with linux then running your favorite
editor can be fine, but if you are serious, then you should learn a
little vi so that you can get out of trouble the odd time you need to
run vi.
