I Like more because he's more funny and realistic

I like more because he is faithful, unlike Wallace, who ditched Gromit in The Wrong Trousers and made him do the washing up under lock and key in AMOLAD, when Piella pretended that he bit her!
 I like Hutch aswell...

For me it's Gromit, because he's so well animated that we know every little thing he is thinking. He's loyal to Wallace after all that've gone through and is a real trooper for putting up with it all, even if Wallace sometimes doesn't really think of the consequences.

I like AND .

Wallace is an absent-minded master. Gromit is the mind of everything. I like them both. That is why my name is Wallace and Gromit Mastermind

Master- Wallace
Mind- Gromit
