I have not found loop antennas to perform any better in terms of gain or noise thAn a long-wire and a proper antenna coil around here.

Oh, they can work great. Check this little 30 sec clip of pulling them out of the noise.

I might mention that this is daylight reception of a 10kw station 400+ miles away across salt water. The effect demonstrated here is TUNING the loop, not just the loop itself.
Unfortunately, if you are totally surrounded by artificial noise its a losing battle.
