Topband: Delta loop antenna

[Bob Lang N3UR]

Would like to hear comments on a 160 meter delta loop antenna verses dipole.
I am torn between erecting a dipole at 250 feet above ground or a delta loop
with the horz side at 250 feet above ground.  I plan to be operating the 160
arrl contest with QRP.  Also would be the option for a 1/4 or 1/2 wave
vertical antenna.  Any stats on call districts where most contesting
stations operate from?  Thanks for any opinions in advance.
