None beats Japan 
saw once on TV, where they got some that pplays music while ya do your business.. warm seats..clean.. nice smelling 
and when ur done.. and close door behind you 
it sanitizes itself.. rinses whole place with chemicals (human safe) and then washes it away and air drys the place afterwards for the next visitor 
 
 
Oh and no discriminating at all. Use for both sexes
