Most all verticals have higher noise levels than horizontal antennas.
Reason, as it is reported, is that man made noise is vertically polarized.

Frankly, I think that the statement, "most man made noise is vertical
polarized" is a myth. How many power lines do you see running
vertically? How many extension cords do you see running vertically?
How many phone lines do you see running vertically? Etc, etc.

I think this needs looked at in a new light. Now most 160m antennas are
easier to construct for horizontal operation--perhaps this is where the
myth got started?
