A mouse called Gerald for me.
I find it depends on how much you handle them early on.
As I say we have five and all the ones we got when they were very young and handled from the off are very laid back. The one we got when he was a bit older and possibly already stuck in his ways is a bit more of a wriggler.
If you get a baby guinea pig and handle it for a short time every day (or near enough) they are very affectionate.
