Anyone thinking 777 is speed stable in turbulence (even light turbulence) has probably never flown it!
Airbus is fine. Each product has it's pros and cons, though I accept one manufacturer's product is much more like the basic machine people would have trained on, and is therefore likely to be more intuitive in the early days. After a while Airbus becomes moderately intuitive too, though some features will always present a challenge. Normally connected with tactile/visual monitoring of flight control/auto thrust inputs!
Like I said. Both products are fine.
