when the report says one thing and the the radar and swell chart say something much different which one is most accurate?
If you trust the person giving you the report, and its near real time, then i trust that over buoy data. Who cares about radar? do you mind surfing in the rain? If the report is anonymous and might be hours old (e.g at a different tide, before the wind switched, etc.) then the report is worthless as an indication of current conditions.
If by "report" you mean "forecast", then you're trying to compare a forecast with actual data which is kind of a pointless exercise...the buoys are accurate for wherever the buoy is (buoys dont measure surf heights anyway) and radar is just precip.
