I've heard a fair bit of talk about how this PDC is better than that PDC, or how you should do it in person, or how online is fine, etc. Or how one covers much more of one thing, while another covers much more of another thing.
That suggests you get a pretty different learning experience with each.
Has anyone taken their PDC more than once? As in, decided "I know how this person teaches a PDC and what they cover. Now I'd like to see how this other person teaches and what they cover."
I've heard from multiple people who have taken multiple PDCs all highly recommend it. I remember Jack Spirko who knows a ton about permaculture has taken a bunch of PDCs and has always learned valuable information at each one. I have done one so far and plan to take more. People can have such different perspectives and bases of knowledge. Plus there is sooo much to permaculture and 10 days really covers so little compared to the potential. I would find it hard to take a PDC online as I am super oriented towards experiential education.
