Your question cannot be answered with the information currently available.
"More Famous" is too idiomatic for anyone 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.
Obviously Buzz Lightyear. Many people do not have Halo, and more people have seen Buzz. Common movie and video game sense dude!!
Buzz Lightyear for people under 8 Adele for people over 8.
Buzz Lightyear. Everyone knows him from toy story. Garfield is just a boring old cat. Also because of his line "To infinity and Beyond!"
Well there not really a answer because people love both woody and buzz and the when baby grow older they'll watch toy story and love woody or buzz so there not really a answer because it's what ever people choose and there will never ever be a most famouse one
Definitley chewbacca. Star wars has been around for far longer and way more people have seen star wars than toy story.
