Firefox 5 or Internet Explorer 9?

For a long time I have always used Google Chrome but it has decided it hates me now and it works great for a few minutes then it just won't do anything for me and I even reinstalled and all the obvious stuff and still no fix, so now I'm deciding which browser to use Firefox 5 or IE9. I know IE has been crap in most previous versions but the new one looks pretty good and it looks like it runs smoother than firefox. Which is faster or is there much noticeable difference between the two? Which has better bookmarks and printing features? Any pros or cons between the two?
