You need to observe the signals over a period of time. Keep the data in a
notebook so you can have an accurate record of what you observed (heard).
You will probably notice that the antennas will compare differently on
different nights and on different signal paths.
For one thing, the angle of arrival for the DX signals will likely be
variable. This will affect how either of the antennas will show up in your
notebook.
Typically (on the lower bands), the vertical will do better on low-angle
signals and the loop would probably do better on high-angle signals.
This is a good reason why you need more than one antenna, particularly if
you are using wires and can't rotate them.

Subject: [TowerTalk] Dumb Question
I have a full size 80M loop up approximately 40 to 50 feet in an approximate
square. I also have a modest vertical, 40 feet tall, with capacitance hat.
Comparing signals tonight, the loop is obviously better for local - about 2
s-units or more. What is surprising, is that the loop is also hearing DX
better. Europe as a whole is approximately 1 s-unit louder on the loop than
on the vertical. Is this anomalous behavior - or is my vertical that
crappy?
