What's Your Feed Reader of Choice?

A few months ago I started experimenting with feed readers to keep track of the blogs I enjoy.

First I tried Shrook.

Now I'm using Net News Wire and overall like it better. The problem? I tried synching with a free NewsGator account online and the online version says I have tons more unread posts than I actually do, and doesn't display my flagged items. Since I like to read entries and flag for later comment, I need to see those flagged items whether I'm on my MacBook, the family iMac, my iMac at the office or another machine.

Could Google Reader be worth a try?
