Best RSS Reader

I have seen many RSS readers around and only about 2 or 3 days ago I actually got into using RSS and I really love it!!
Can anyone please tell me what they think is the best RSS reader? Just to let everyone know, I want software! Not like Google or Yahoo! or even an add-on for Firefox. Just purely Software please.
What do you use or you think is the best?
