who do you think is real superstar of south india

I and my family love watching Malayalam movies starring Dilip. We find the movies very entertaining and most of his roles vary from movie to movie. I used to love watching Mohanlal movies. However after a spate of not so enjoyable films we have moved on. Most of the actors in the Malayalam film industry are gems. Noteably KPAC Lalitha, Oduvil Unnikrishnan, Nedumudi Venu, Thilakan etc. The main stars actually bask in the light of these gems.
