Me too. Some people think it is primarily useful on low bands, but I use
it on all the bands 40 thru 10 meters (which are the only ones I
currently have antennas for).
I am using an R8 vertical for transmitting and one RX channel, and a
Pixel Loop for the other channel. They are only about 25 feet (7.6 m)
apart and are both vertically polarized, but there is definitely a
diversity effect. I find that QSB is greatly reduced and CW copy is much
better with diversity active. The only times I don't use it are when
there is too much noise on the vertical or when I need the subreceiver
for a pileup.

I use diversity receive quite a bit. It was actually the main thing that got me
looking at a K3 in the first place…great feature.

The frequencies of the two receivers in the K3 are locked together for
diversity by sending identical instructions to the two identical
synthesizers which also share the same clock oscillator.
RF phase doesn't need to be coherent for diversity reception as
implemented in the K3, because the two signals are only combined at
audio frequency (usually between the operator's ears). There may be
small difference in time delay (group delay) through the roofing filters
in the two receivers but in practice this doesn't seem to be a problem.
