How about Mozilla Thunderbird? It supports both RSS and Atom directly in the mail reader and works quite well. Whether you like it integrated with a mail client is probably up to personal taste, but some people do.

Gnus supports converting RSS feeds into virtual newsgroups, just as it allows converting mail, digests, google output and just about everything else you can imagine into virtual newsgroups :)
