Self serve vs managed campaign. What is used most by super affiliates?

Just out of curiosity.

1. Is more possible to make $xxxx to $xx.xxx day with self serve or managed?

2. The quality of traffic has differences between a respected self serve network vs managed?

3. Is wise to transfer a full optimised profiting campaign to managed, so you can focus on creating other profitable campaigns?

Thank you for the answers 🙂
