A350 vs. A330:
Much better Autothrust fidelity on final.
Same flare height. Much gentler/flatter flare, though this may be a result of perception from 'awkward' seating position to see through HUD correctly.
More forgiving touchdown. No awkward front axle touchdown on de-rotation, due bogies being level, or slightly toe-down upon completion of flare.
Much faster de-rotation. Due nosewheel further forward, you feel it ...
