Dave Seville, he treats the chipmunks and chipettes with love and care :)
Ian’s presence had nothing to do with Dave grounding them, that’s just an observed coincidence.
I think it’s no contest, just about everyone will choose Dave over Ian. Unlike Dave, Ian hasn’t had nearly 60 years of prominence in the franchise, where as Dave has appeared in all of the series and movies. Ian just isn’t as recognizable because he’s only been in the live action movies and was not in the source material they’re based on.
What do you think?
