I leave the task to DrDre, but sometimes I like to post my own comparison, just to spur him to do his best! (^^,)
About AR: I love to have as much picture as possible, and I hope DrDre will change his mind, and use all the sides information, becase they are mean to BE there! On the height: 548px is the perfect size, as it's exactly 2x the GOUT, and gives better results and less artifacts on the vertical direction.
