Protopage vs. Pageflakes

Ok, so now I've spent some time playing around on Pageflakes and can now make some detailed comparisons between the two.  I was hoping that Pageflakes would offer some of the features that I don't like on Protopage, but it has its own ways of annoying me, so I'm not sure yet which one I like better.  Here is a comparison.

Ads	Ads not inappropriate, located at top of page, can be hidden by scrolling below the ad.	Ads takes up space on page, can adjust size, but position is fixed where it can't be hidden, what I've seen has not been inappropriate.
Widgets	Widgets are difficult to browse, can't search	Called "Flakes", easy to search
Widget Features	There was nothing here that I didn't find on Pageflakes. Main problem, I could not change the font size in widget, making it difficult to size for my students to see from far away.	There is a customizable Flake (called the Anything Flake) that lets you compose you own content in a simple Microsoft Word-style composer. Includes adding images, typing text, changing fonts, editing html, etc. Another Flake I like is the one that allows me to upload and share files. I was interested in sharing class files on this page for students to download at home. Very cool!
Layout	Can customize size and location of widgets freely.	Restricted to Pageflake layouts. Can't position or size flakes freely.

Like I said, there are tradeoffs that make it hard for me to decide which I like best.  I do like both better than iGoogle in that they are easy to share and make public.
