The advantage of connecting the KPA500 to the K3[S] is that you can
select bands with one button. Useful for those of us who forget what
band we wanted as we're stepping through them with the BAND UP/DOWN switch.

I've never considered doing this. Except when there's development for
brand new products, Elecraft firmware typically updates once or twice
a year. We're seeing a bit more than that now because of the new K3S
and P3TXMon.
At home, I use real hardware RS232 to control the two K3s looped
through P3s in my SO2R station. That works with K3 Utility, P3
Utility, N1MM+, WSJT-X, and DXLab Commander. The only control lines to
my KPA500 and KAT500s are PTT via the RCA connectors.
Both the KPA500 and KAT500s are very good at RF-sensing to do their
own band-switching. I use their USB connections only when I want to
load new firmware, and I do it by simply moving a USB cable from one
unit to another. I use the AUX bus only to feed band decoders for
switching antennas and bandpass filters.
For FD and CQP, I find myself using the USB cables because the
computers don't have hardware serial ports.
