Horses for courses!
The Robin is great in France cos every little airfield can mend it.
The Warrior is great because they are available to hire just about anywhere you go in the flying world. Robins aren't.
If you want to fly into and out of very short fields, you need more power than the Warrior has - so choose its big brother, the Archer.
If you want aerobatics, talk to an aerobatics expert: Chipmunk, Moth, Pitts spring to mind rather than Robin.
No one aircraft is all things to all men; get past the "tifosi polemics" and try them all, to see which you prefer.
