This question has been asked a million times. In my opinion it highly depends on what you want to do with it. Look at http://distrowatch.com/ for the more popular ones.

With the risk of forgetting a number of distros: Xubuntu, DSL, LFS, Slackware

On the PIII the shortage of memory is what is going to be more of a problem than the cpu. I have a PIII 1ghz with 512mb that I use as a media server. It run Centos5 without issue. At the price of memory now I would think it would be better to keep both machines on the same "blood line", ie I run Centos5 on my servers and F7 on my desktop.
