Love Airbuses due to the fact they appear to have more legroom. Hate 767s even with the 2-4-2 seating down the back. Will try really hard to avoid long haul on 767 unless I'm in J, and even then I'm meh about it.
Love the rocket that is the 757 but that's just because of the enthusiastic take off
Love upstairs on the 747. Smaller cabins are better than bigger ones.
