I wrote my own and integrated it into my website. It is extremely fast and is customised exactly how I like it.

As always, if you want a job done properly…
Netvibes uses the boxed concept which is excellent for surveying vast numbers of feeds at a glace with all the extras built in. There is a OPML import to give you a let you test at minimum effort and it is much faster (speed/ergo) than pageflakes.
