Service will be equally crappy unless you can miracle yourself into F on any of these carriers. Also, your seat will be equally crappy unless you can miracle yourself into an exit row, preferably on the 767. Alternately, the ABC side of the first row of coach of the 757 is ok, as long as you don't mind people waiting for the forward lav being near you, or the slightly cooler cabin temp as you get closer to 2L, the exit row door.
