Cannot compare with rajesh khanna, his stardom was on another level altogether. In his generation it is definitely an incredible run. 7 blockbusters and 1ATBB is an amazing feat, had tube light not gone wrong, ek aur blockbuster add ho jaati.
Aamir is a different case, but unique in his own way, one can argue less movies but even tougher to give ATG'S with such regularity. Dont want to choose between AK and salman, both have seen an incredible run.
