Since I'm 6'2, I prefer being on any plane that gives me maximum legroom. I was flying from East coast to West coast, back when all they had was a projector system beaming on the wall and in comparison to having some guy beat my headrest for 4-5 hours, I'll take the old projector system. If all the screens do is play a movie or TV shows it's fine, Delta's systems for a while had games to play on the touch screen and that's where all the headrest beating came in.
Here lately, most all the flights I've been on had no screens, but USB plug ins for phones and tablets. Plus having flown so much over the years, I'm a gifted sleeper on a plane. In fact, I'm like Pavlov's dog, within 30 mins of getting on a plane, I'll be asleep, which again is why headrest beating is extra annoying to me.
