Note that Devise and CanCan are orthogonal... you can use both, or either. Authentication is something that doesn't change a lot after it's set up, so you might write it once and forget about it. It's good if you want to keep it simple. I suppose you might decide to support a new mechanism like OAuth or OpenID (for facebook/twitter/google login), and that might be harder to add to your own existing system later. Devise is maybe harder to understand, but that is the trade-off, it takes care of the complexity for you.
One immediate smell I get from Ernie's tutorial is using method_missing for roles... I personally wouldn't do that, and @user.is_a_user_or_admin_or_superhero_or_demigod_or_chuck_norris? is a bit ridiculous. I would pass on this tutorial. Devise + CanCan is basically plug & play, but you can still customize a lot. I would recommend it. Also for security, you are covered by more eyes on the code.
