It's not size that gives a smooth ride per se. It's mass and wing loading.
Driving wing loading up smooths the flight, but kills efficiency. 777X will have a larger wing to reduce wing loading and improve efficiency. Will that result in a worse ride? Maybe. Maybe not. That depends on how flexible the new composite wing is and how effective the active gust load alleviation system is

Will 777X be noisier? Maybe. Maybe not. The 777X has the same external diameter but larger internal diameter resulting from thinner sidewalls with thinner insulation. That portends a noisy cabin. But the new insulation is supposed to be much more effective than the old insulation, resulting in an allegedly quieter cabin. Boeing has also been working on active cabin noise cancellation systems, so maybe they'll add that. What we do know is that like the 787 the windows will be larger, the cabin altitude lower, the ceiling higher and more "spacious", and the cabin humidity higher. We'll have to wait and see how all this stacks up against the A380 and A350 for overall comfort.
