Standard Answer #1: It Depends.
Both are good, both are acceptable. The differences depend on what you prefer.
Bortaks = Double 20% Fast Cast, +1 20%, 17 energy conditionally.
Ghials = 20/20, +1 20%, 15 energy unconditionally.
That said, personally I use the 20/20 crafter wand, and switch between Bortaks Cesta (9 or less minions) and Konruu's Fervor (10 minions)
