I'm mixed on the A330 bulkhead.

Love not having anyone in front of me but no storage space and if you are on the taller side there is a wall so you can only stretch so far. I'm 5' 11'' and it's fine for me but close (would think maybe 6' 1'' and taller might start to feel squished)

On the flip side the exit row is basically unlimited legroom but you get people waiting for the bathroom who will come into the space -- not a big deal except around meal time when you get a big rush and it can get quite crowded.

Other downside of the exit row is the IFE is in the seat so you can't watch anything during taxi/takeoff/landing because it has to be secured and put away.
