I have not had a chance to ride the Desierto. Only DP has tried both to my knowledge. But the Desierto quality appears to be better and all the owners are satisfied. I am very happy with the shape and performance of the Aeroflow but the material could be better quality. IMO I would rather get something that works well and looks good for years. Desierto appears to have an edge in this regard.
