For me diving is much easier. You don't have to worry about flailing your arms. The one caveat is that while the "Superman" photos look great, if I go in the water at that angle I will be hurting for a long time. At some point during the dive you have to put your head down and hands clenched abvue your head to break the water. I have been cliff diving since my teenage years.
Every year my wife tells me this is the last year. I only do one or two a day.

Bob
