I flew the 777 in HD J config 3 times; 2x in J, 1x in Y. In J if traveling with your spouse, it is fine, If traveling alone and you do not have access to the throne seat OR you are not sitting in the center then yes it would suck to crawl across a stranger. Y blows; not only are you crammed in the smallest seat that you can imagine but some very DUMB person decided to install the AV controls right under your elbows.
