When in Fangorn Forest, Aragorn drew Anduril against teh Cloaked Gandalf, and suddenly dropped it, saying it blazed with a sudden fire. Now before you go and say "IT WAS TEH HYPERBULLZ", Voldemort's staff is made of wood right? Well if you super duper heat wood, it catches fire am I right?
Lifting a staff takes more time than to point a wand.
Facts are.
Voldemort can spam teleport and effectively does so, making the chance of Gandalf hitting him not very likely.
Voldemort has several spells to incapacitate Gandalf and one that will kill him with a single casting.
With a gesture Gandalf can be disarmed.
