[Elecraft] K3 2 meter capability: internal K144XV or XV144 transverter?

[Phil Hystad]

What is the better solution for adding 2 meter capability to the K3, the new internal K144XV or the XV144 transverter.  I see that the power output of the K144XV is 10 watts and that the power output of the transverter is about 20 to 25 watts.  Let's assume I would want a 100 watt PA, does it make a difference on whether I have 10 watts drive or 25 watts drive?  Since I have not looked at any such linear amplifier I am not sure what the drive requirement would be.

I have not exhaustively read all the documentation available on these two but I was curious if there were any "stand out" reasons for choosing one over the other.

Thanks,
