Zone or Man Defense?

[Canon reeves]

Which kind of defense could you see being dominant at competitions? The advantage to zone is you don't have to travel much for an assist, but if you had a really good defender on your team would it be worth not getting that third assist every time for you defender to stop the other team? We figured a robot with a 5' blocker that can also catch would do really well against lower shooters, so would it be better for that robot to focus on catching or stopping their opponents offense?
