Share 'Kindle Fire vs Nook tablet( which one's better??)'

I'm having a hard time choosing from Kindle Fire and Nook tablet. At first I REALLY want Kindle fire. It's good looking, has great features and it embodies the basic necessities that I want in a tablet/ an ereader. But that was my first impression of the Kindle, by the time I have search about Nook tablet it seems that I'm in dilemma of what to choose, REALLY really confusing... what about you?…
