Many times, a 28mm will render a scene in a less-distorted manner at the corners/edges of the frame. A 24mm and a 28mm are two, very different lenses. The thing is...each prime lens is "its own thing"...and many,many times too WIDE of a lens angle is as bad as too narrow an angle! Me, personally? I prefer longer lenses for landscapes, for bigger background objects. The 24mm makes things look small and far-away, the 28mm less so,and the 35mm even less so.
This is one of the things that experience teaches; there is not one,right lens length. For some people, 28mm was considered the "true normal lens" length...and I am not kidding about that! But that's a story for another post.
There is a LOT in favor of the 28mm as one's wide-angle lens on 24x36mm capture size cameras.
