Absolutely.  Unless you are looking for a trail/backpack radio, the
added flexibility, features and user interface of the K3 is hands
down superior to the KX3.

Yes, with its dedicated line out and line in capability - including an
independent digital to analog converter for data out - the K3 is vastly
superior to the KX3 for digital work.  Note however, I would not be
using any amateur rig for commercial experimentation as you will likely
want to be working at UHF or low SHF for the short to medium range
medical data communications.
