I personally prefer using <h1-6> and do not see, why always using <h1>
may be better.
Furthermore I think that using <h1> in this case is quite irritating.
The HTML 4.01 standard says the h1-heading to be most important, the
HTML 5 standard defines it as having the highest rank. It is in my eyes
unintuitive having only headings of highest rank in a document. (Yes, I
know, that this isn't quite correct, but from the view of a simple html
author who doesn't really care about outline algorithms, this is true.)
What would make much more sense, is to omit the rank fully, so only only
has to write <h>.
<section>
<h>Rank of this title is to be found using the outline algorithm</h>
<p>Yey, content!</p>
</section>
Furthermore this ensures that one can easily style a document that uses
both the <section>ed variant and the <hX>-ranked one without having an
extra selector.
Beyond that, using <h> instead of <h1> would even be more backwards
compatible to the HTML 4 use of headings.
