It doesn't really matter.
Now, there's a lot of people that say it doesn't matter if you have multiple H1's on the page, I just think that we know that the algorithm looks at that. So why have multiple H1 tags on a page.
You have one concept that the page is about the H1 should say...
This is what this page is about and if you want to break your content up into subsections, and have little sub headings there, use H2, H3, H3, H4, H5 and H6, whatever, it doesn't really matter what the number is past the single H1 that you have beyond that.
It's really just whatever you have your CSS set to so that you know you want it to be a consistent size and doesn't really matter.
