Tokaido Shinkansen N700/700S. There are lots of upsides to HSR such as extremely good seat pitch and total absence of security theater, and it's true that the airliners has a loud constant white noise, but when it comes to noise and vibrations, I feel airplanes less... intermittent and less interrupting. Those Recaro camp chairs aren't too bad either.
