I know of a friend of a friend that picked up a pair of Divas while owning the Betas, and the Betas went up for sale afterward. As I understand, it wasn't a completely obvious decision, but unfortunately I don't know the particulars that swayed him. If I can find out more, I'll post again.
As you may already know, the Divas will have somewhat faster bass, but you'll have the dipole cancellation that should probably make for some unevenness in the response down there, while the Betas will be very flat except for any room modes that both speakers will exhibit.
