After using a healthy dose of gadgets I can tell you:

For pen-writing; Pen gets 10/10, Resistive-touch gets 8/10, Active-Digitizer gets 7/10, and Capacitive-stylus gets 5/10.

For finger-friendly; Capacitive-touch gets 9/10, Resistive gets 6/10, Pen gets 0/10.

For features (multi-touch etc); Capacitive-touch gets 8/10, Resistive gets 7/10, Pen gets 0/10.

I think the best combination of touchscreen gadget would be a multitouch capacitive touchscreen with a high-quality Active-Digitizer (N-Trig).
