Airbus or Boeing???
For me it is just a question of attitude. I always liked the planes I flew. When you change brand, you change philosophy. But I found it really easy to adapt.
I flew B737 (200 to 500), the famous DC10 and I'm on A330 since 8 years (after 2 years of A340). I've more than 18.000 hours and still like to switch off everything (A/P, F/D, A/T) and can tell you the bird is flying great even in rough conditions.
Ecam? very helpful in case of...
Side stick? yes, it's rather sensitive in the beginning but a few hours in the sim and you feel it.
Fixed throttles? switch off the A/T whenever it suits you.
The attitude limitations?? Tell me how often you would need more than 67° bank with pax on board.
But if a Cy offers me place on B777 I would not hesitate to take it.... just for the pleasure to discover another plane!!!
Happy landings
