The Darkstaff VS The Sunstar

Which is the most powerful object in the universe, the Darkstaff from the Old Republic Sith or the Sunstar from the Ewoks show/comics?

BTW, sorry for being inactive for so long. If you don't remember me, I joined a few months ago, but only stuck around for a week. I will try to be more active.

Sunstar

Any particular reason why? Seems to me like the Darkstaff has more destructive power.
