I have both and the KX3's NB is definitely much better than the K3's (although still worse than the Icom NBs). Probably a question of the newer DSP chip in the KX3 and maybe updated DSP code, too (on which Lyle, KK7P, could chime in).
One of the (few) disappointments of my K3 is the NB. I've never found any settings which are effective against power line noise under any conditions, even on a quiet band. My old FT-1000D NB, on the other hand, can be very effective against that same noise, provided the band isn't full of strong signals. Neither is useful in contests, of course. Given the way the NB's in both transceivers work (wide filter ahead of NB), neither can be effective with strong signals nearby. My dream is that Elecraft could provide a way to use the subreceiver to detect noise outside the band, and control the NB in the main receiver. Or perhaps some day I'll figure out how to do that myself. However, first the K3 NB has to work in the absence of strong signals, which it does not.
