I think the A330 is the perfect aircraft to fly if you want to do some smooth landings, or just to fly in general.
Why is it so perfect? It all comes down to the landing gear. The back gear is very high up for an aircraft, which helps the back gear be able to glide down the runway letting the nose be gently settled. The gear tilt also helps smooth the landing by making contact with the surface first so other parts can be deployed sooner. While it may be argued that planes like the 777 have more than one pair of rear gear as well, these are very short/stubby rear gear which allow a shorter time for the back to be let down. Also the fact there are 3 pairs on the 777 make it feel almost forced. Just look at these clips of A330 landings.
