Yes, Samir, I have used both. I like the KX3 and its internal 2m option.
The receiver is very sensitive and as it uses a 50MHz i.f. it covers the
whole of the 2m band (up to 148MHz) comfortably. However, the main
drawback is that the power output on 2m is only about 3.5W and somewhat
less when using internal batteries.

When using the K3 and XV144 combination, with an i.f. of 28MHz the
bandwidth is limited so it can only be used up to 146MHz. The power
output is up to 20W SSB and CW or half that power on AM/FM and data
modes.  One answer is to install the K144XV which switches crystals for
144-146 and 146-148MHz. However, the power is limited to around 10W on
any mode.

Hence, all three systems have their pros and cons. I hope that helps.
Doubtless others will comment.
