Where can I go for a web page that has a direct comparison of the
Aries 1 payload capability versus the Delta iV Heavy and the Altas V?

It's hard to compare the two since they have completely different missions.
That said, I think NASA's ESAS report looked at them. But people have been
complaining that this report lacks some of the detils which are contained in
(missing) appendices:

I think you want:
