Personally I find a great photo , one that has best of those 2 worlds. Some great photographers , were lucky enough find themselves in right position at the right time.
I only disagree with the "lucky" aspect of this discussion. Yes, sometimes it's pure luck you are at the right place at the right time for something extraordinary, but great photographers normally do a lot of studying and planning before shooting - scouting locations, checking weather, waking up in early hours to hike to a special location, waiting for days until they get that special light for their subject.
