From what information we've been given so far about Groundhog Day, this is apples and oranges. I like Matilda and Tim Minchin quite a bit, but it's material that is very different from Hamilton.
I have to agree with what other posters have said before--I don't think there's a need to compare every show and make things a contest. I think Hamilton is outstanding. I also feel that way about SITPWG and ACL. But I don't think I can, or moreover, need to compare them. They're such different beasts. What makes them enjoyable and special to me is the unique emotions and reactions they cause for me.
