I like both. Both have pros and cons. I enjoy table top due to the much faster pace and the camaraderie there as Daishain mentioned. Play by post can get frustrating waiting for the next round or for someone to post. However, In the table top groups I have played in there are always one or two immature players who take away all immersion aspects of the game.
The big advantage for play by post is the immersion. I don't see or hear the people I roleplay with. I roleplay with one person who plays a comical gnome and another that plays a dwarf. I see and hear the characters in my mind when I read their posts. In a tabletop game I would see and hear Bob or Sarah and it would take away from that. The immersion and roleplaying is the most important part for me. I come from a World of Darkness background and that has had a big influence on me. Edited: Kyrroeth on 2nd Dec, 2016 - 6:16pm
