I prefer 90x40 horns because they provide a good pattern in-room, especially when used in cornerhorns. That's a unique situation because directivity is equal throughout the entire audio band if all horns have a 90 degree pattern. This makes the reverberent field uniform, and I think that sounds most natural. But all of the horns you've mentioned sound very good to me.
