I think you should rephrase your question into two questions:
Which Professional-Sport Do you Prefer watching In-Person?
Which Professional-Sport Do you Prefer watching on TV?
and
Believe me there is a BIG difference.
Being at a game changes your whole perspective, energy level, and involvement in the game. HOCKEY RULEZ In-Person, and so does BASKETBALL but both may not seem so great watching on television.
Basketball gets my pick for overall entertainment value.
