I'm 6ft 1 (1.84m) and I would avoid the bulkheads. You lose some leg room (but get the knee room), the seats are slightly narrower for the TV screen, a fellow heffalump may well be seeking to sit next to you, on some aircraft you lose the window, most aircraft you lose access to the front seatback storage and water holders. You do gain the bassinet table top but it's a bit high up, plus there could actually be a baby in residence......
