SimplePie seems as robust as MagPie and it’s got some nicer features. It’s significantly slower when pulling from the net, but it is insanely fast when coming from the cache. Unfortunately, you’re mostly pulling from the net.

This is Ryan from the SimplePie project. It should be noted that none of the aforementioned parsers do ANY data cleanup except for SimplePie. This is the trade-off. SimplePie can take longer, but it gives you much more usable data (including the correct handling of Atom feeds). If you care less about clean data and more about faster parsing, check out the set_stupidly_fast() configuration option (http://simplepie.org/wiki/reference/simplepie/set_stupidly_fast).
Hope this helps! 🙂
