Welcome to the forum, nj1.

Drupal is normally regarded as the more powerful one. I have not used Drupal 7 but generally speaking Drupal is regarded as a very hard CMS to use from a development standpoint. Asking whats the best, easiest CMS is a tricky question. More features and more ability always comes with more complication and a higher learning curve. The ease of use also varies with what you want to do with it, what are your intentions with it?
