I haven't tried Digg or AOL Reader since they aren't available. My usage is basically a headline view of all the feeds, I have them in different catalogs. I will scroll through them to see anything worth to read, and open it up as a new tab as i go through them all.
Newsblur is very non Google Reader like. I suppose it fits some of the pattern of flows of a particular niche. But not me.
Yoleo is great except it doesn't work very well with non Unicode Feeds and it is quite slow. Unread count is overlapping. I think it is a solid app given some more time to develop. But I use Reader everyday or every 4 - 6 hours i cant afford to wait.
Feedly web works well so far. It is the closest thing to Google Reader in Headline views. The thing i dont like are performance and slow scrolling in some cases. But it generally fits me well.
The thing is, there is nothing wrong to try everything out. It is only a click of a button for your Google Login.
