If Dooku can "defeat" General Grievous - and especially if Obi-Wan can - then Anakin sure as hell beats him. Don't feed me that crap, trying to downplay Anakin. According to you, Dooku can WTFpwn Grievous, but Anakin can't take him?
Don't feed me that bull. Dooku and Anakin are very close in skills and abilities with Anakin being the more powerful of the two. Kenobi may not win against CW Grievous - and that's when Anakin would go down.
But Anakin being unable to defeat Grievous? This is when your fanboyism disgusts me. Downplaying other characters so your favorite gets to shine? Don't do it.
