[Elecraft] How good is the KX3 CW decode?

[vtnn43e at comcast.net]

I am thinking about getting a KX3 and am wondering how good the CW decode is considered to be? Currently I use an SDR rig with CW Skimmer and it works very well but I would like to have a portable rig for car camping and it would be also be handy to have one just in case of a zombie apocalypse or attack by Gojira . 

If anyone reading this uses a NUE-PSK with another rig how does that compare with the KX3 CW decode? 

Last of all how good is the KX3 CW decode in marginal conditions? 

Yeah, I am aware that I really should only do CW by ear but my ears are not so good and I really like using software to decode CW. Currently I have 177 countries confirmed in LOTW with CW Skimmer and my SDR.
