Your question cannot be answered with the information currently available.
"More Famous" is too idiomatic to provide an adequate answer without poll data from various areas & age groups, perhaps even from different socio economic groups.
Without any data of this sort there is no way to really determine which person is more widely known to the general populace therefore any answer would really be speculation, opinion and/or conjecture from the individual who answered.

Incredible hulk by far
Well they are both the same. Because Lady Gaga is a singer. And the incredible hulk isnow popular again because of the new movie The Avengers.
Shrek because people talk about him more no hulk is cuz little kids like him and shrek but grown ups like hulk more than shrek cuz shrek groses them out somehow but hulk doesnt so there are more people who like hulk more then shrek.
There is not enough statistical data to answer this question properly and without the adequate amount of information (via poll or survey data), any answer would simply be opinion based and not a substantial answer.
