Between only skeet and trap, that's a given. Skeet.
If you can find one close, a 5-stand can be great because they can throw crossing, quartering, tower, teal and just about everything else you might like to shoot for practice--all in a close area where it's easier to get many shots in in a short time.
A sporting course would be a second best choice, IMO.
But if all you've got is skeet or trap, well....
How many ducks have you taken a shot at as they flush up from the water away from you on some slight angle?
