Hi A37575,
Interesting question. Having flown both types, the loads on the side stick of the Airbus are tiny compared to those required on Boeings. I sometimes wondered if I was actually physically lifting the aircraft off the ground myself when the stab trim didn't exactly match the loaded distribution of the passengers.
As for hands on thrust levers - I remove my hand from the TLs at V1, and (on the Airbus) place it on my knee (because I can't think of anything else to do with it until I have to select a different thrust gate). I've seen other Airbus pilots put their hands back on the TLs and I still wonder "Why?"
