Well being a former super member of Personality Cafe, and being a senior member here, I believe that I am definitely qualified to answer this question.
The pros of personality cafe:
-It has about 10 times more users than this site so it seems like as soon as you make a post, there are about 10 replies to your post in less than 20 minutes.
-It has more knowledgeable people on topics such as MBTI and the enneagram.
-There is more to do there.
-It has a lot more articles on various enneagram and MBTI related topics.
The cons of personality cafe:
-The moderators are crooked as hell and the site is corrupt as hell.
-You never know when you are going to get banned there. They have no set in stone rules on how many infractions that a person needs to get banned, and so many people have been banned completely out of the blue on that site.
-Because there are so many users there, and because so many people answer your posts, it seems like you never get anything done that day in real life if you go there. I will literally create like one topic on Perc, and I will still be answering posts from that one topic like two hours later. It is very bad for anyone that actually works or has a life.
-The pros of typology central:
-The mods are clean and are not corrupt scumbags.
-They have very clear rules on how many infractions that it takes to get banned, and don't just ban people out of the blue or just because they don't like a person.
-It's not so fucking political.
-It doesn't have that many users so it provides you with just enough entertainment to kill time, but not so much that you're going to get nothing accomplished that day.
The cons of Typology Central:
-It doesn't have that many users so not that many people answer your threads.
-It's a lot smaller than PerC.
-It doesn't have as many knowledgeable users on it.
-It doesn't have all sorts of new article on enneagram and mbti like PerC does.
