The first is bloglovin'. I really like the look of this one, however it's had trouble with the influx of people from Google Reader and has been hard to get into. It puts your blog list into alphabetical order, but I kind of like the groupings I can use with Google Reader.
The other is Feedly. It imports your feed and keeps your blogs in the same groups they were part of in Google Reader. It has a few other things you can do - like change your background color, style of layout, type of organization. You have to use Firefox for this one which is a problem if you use more than your own computer. I'm leaning in this direction right now, but am trying both out for a bit to see which stands the test of time.
My friend Sandra, at Diary of a SAHM did a more in depth post with information on several sites. You may want to check it out if you are still deciding what to do.
Do you use Google Reader, and if so - have you found a replacement yet?
