I flew both........
The avionics and weapons system in the Tornado is superb but its a pain to fly............
The Buccaneer was a joy to fly but the avionics and weapons system was a pain.......
So...... as a pilot, the Bucc gets my vote..........but I'd rather go to war in a GR4 as its all well and good enjoying the ride to the target but not much use if you can't hit it with anything useful when you get there.
