I strongly prefer the direct link to the paper. Downloading and viewing a PDF is not so burdensome that this is a problem. I get the abstract at the top of the paper and if I'm no interested I can just close the tab that's showing the PDF same as closing a web page.

I strongly prefer the cite-able link to the pdf. The link points to the PDF, but the PDF does not point to the link. The link points to all versions of the paper.

As it turns out, the URL of the pdf is cite-able.

But it doesn't link to the versions of the paper.

You want to save one click of the mouse. I want to save having to reverse-engineer the parent URL.
