Goku is way more famous.

Sadly Lady Gaga is more famous than Goku by far
according to the internet: Ben 10: 2,250,000,000 results Dumbuldore: 15,400,000 results but that's the net not the real world so it could possibly be more people know Dumbldore but not everybody knows Harry Potter so probably more people know Ben 10 anyway.
Justin Bieber
Definitely Goku. He's more of a main character and he's the only one i can remember from when I watched the series about 10 years ago
Goku is more famous it is just a fact
