John I have not had an r but several x's and a tenere, the main issues will be for you as follows if you want a ten.

Seat holds you, no room for movement, if you buy it try it and get the seat reprofiled, that will cure it.

The wind blast is better on the ten compared to the r but if you had a touring screen on the r then the ten is no better blast wise.
Riding the ten is good, it feels massive where as the r/x is small.
You will be ok with it's height as you are tall.

Final comment if I was to get another xt, no question it would be a ten.
