Drigg vs Pligg

Drigg was started as a bug free drupal based alternative to pligg. At least that's what I think. I haven't used pligg in while but, from the looks of it, it looks like pligg has evolved a lot since. So, where do u guys think drigg stands in comparison to pligg. And is drigg really worth the effort and resources put into it compared to pligg ? I know for someone who already has a drupal site drigg might be the only option but, for most people who just want a stand alone social bookmarking site what do u think is a better alternative ? I am guessing people here are going to be biased towards drupal and hence drigg but, I'd like to know ur opinion anyway. I'm sorry if this isn't the right place for this.
