i can only report on seat 11E, which is my preferred seat on the 74E. recline in EC is definitely greater, but i didn't feel seat comfort improved much. its still a hard economy seat. as for added leg room, 11E still has miles of space in front of it, so no improvement there. see my pictures below:
