The loop you reference is a broadband, amplified, rx only loop - not really a (small tuned) magnetic loop.
I use an LZ1AQ setup with a horizontal loop, vertical loop and a vertical dipole - switchable via the LZ1AQ's onboard input relays. Both loops are significantly less “noisy" than the dipole and the vertical loop is usually quieter than the horizontal loop. I also have a rotatable, vertically mounted, small tuned loop (MFJ) which can, at times, beat the LZ1AQ loops on rx SNR because of the tuning - the tradeoff, of course, being bandwidth limits.
