Would I get a more overall picture of my ancestry if my sister were tested as well?

Her being XX and me having that that pesky Y chromosome and the XY pairing. Or would me and my Y chromosome give her a better base than if she had done the test herself?

I know that the X and Y chromosomes determine sex and do not undergo much if any changes as they are passed down.

But that's something I have known for quite a while and maybe it's not so set in stone anymore. So I'm wondering if, because of the Y chromosome, would the DNA of a brother have a more complete profile than that of a sister?
