yes the desert hairy is in my opinion a lot easier when it comes to cleaning. they are also much more aggressive and are less likely to sit in a burrow. the emps look more impressive in my opinion with the big claws, but the desert hairys have attitude.
you can make them more visible in the cage too by using black sand to contrast with them, whereas emps have to have cocofibre which is basically the same colour as them.
i would say get the desert hairy if you want a species which shows off a lot and is visible, but you can only keep one per tank because they are non communal.
they also seem to have shot up in price recently so have a good look around for the best deal before buying, and try to get an adult, molts dont go well in captivity with this species.
