Do all three if it fits into your schedule
. For me there is not a question, it is duck hunting without a doubt. Alot of it would have to do with where you are located at and what would be the best for that area. Are you able to travel to other areas to hunt if you don't have good hunting for all three, is it in the budget, ect.ect.ect.
I love to do all three, but I am a terrible shot with a bow, that is why I go slug hunting. I am getting way to fat,old, and out of shape to be walking multiple miles chasing roosters all day. That is why I choose to wake up at an ungodly time in the mornings, go out in wet, cold, miserable weather, and sit in cattails waitinf for birds to dump into my decoys. What could be better.
Just being in the outdoors watching a sunrise, or sunset is great no matter what your doing
