If one is quite tall, as mentioned, the bulkheads can limit legroom. I personally like them, since I don't like someone reclining in front of me (if I can help it).

The bassinet table can also be useful e.g. in putting one's finished meal tray on to get up and use the loo when others are busy trapped by their meals!

Anecdotally, my op-up chances seem to be higher when I'm in a bulk-head seat, but this shouldn't be a major reason to choose!

Downside: less time to use IFE compared with the regular seats, sl. less seat width. On most recent flight, I was unable to recline, and thought it was a seat issue, but apparently I didn't try hard enough!
