From a purely aesthetic point of view, I just dont like the 23, it looks like it isnt quite sure what it wants to be... is it a flying wing, or a more traditional fighter?
The reading I've done on it suggests it did have some advantages like better range and low speed maneuvering, but all in all the 22 is the much prettier bird IMO
