I noticed the dB S/N numbers are Much higher on the ferrite, and the dBu numbers are much, much higher on the air core. As the numbers tell, the high signal strength does not help much if the noise is higher too.

This is a problem with unbalanced air-core antennas. They tend to act as loops and random-length pieces of wire. They are more susceptible to picking up noise. A balanced air-core loop is very quiet.
