I thoroughly did enjoy them!!!

And...I would have to say the Elder Wand is the most powerful...but not because of it's wood and core, bit because it has been through so many different and powerful owners.

I recall reading that wands retain some of the power of their master.

That being said, the wand qas owned by bot Grindiwald and Dumbledore before going on to be Draco's then Harry's, but used by Voldemort. And those are just the four owners (and one user) that we know to be fact...

So I say it's most powerful based on it's experiences and owners...
