I also was comparing between RSS 2.0 or ATOM 1.0 because they quite similar in the practical sense (unlike RSS 1.0’s use of the RDF extension). This was just a matter of taste; I wanted something that browsers could readily open in case users didn’t have dedicated readers. In my experience, RDF is a bitch to open (considering it ultimately is still XML) unless you have an application that recognizes it. Plus the fact that people often don’t realize that you’re supposed to right-click and copy the feed URL (for use with your reader) instead of actually navigating to it – it would be good to have a fallback where those without readers can still see the code and be somewhat pointed to the right direction.

For the comparison, I came upon this site/article, and ultimately decided on Atom. I also tried styling the RSS feed, so you can try clicking on the URL and see the XML styled via CSS. I wanted to put some info table a la Blogger which tells people that the feed is meant to be read in an RSS reader, but the <info> tag it was used with is now deprecated. If anyone knows of an alternate, valid Atom 1.0 tag I can use for that purpose, please drop me a line.
