Who is the greatest: Wasim Akram or Glen Mcgrath?

Though Mcgrath is foul mouthed and aggressive, no one can deny his talent. He is my favourite fast bowler. Akram is also great. But many people in this cricket section speak more about Akram than about Mcgrath. Akram holds the record for most wickets by a fast bowler in ODI. Mcgrath holds the record for most wickets by a fast bowler in Test Cricket. But Mcgrath is very economical in ODI. So, who is the greatest fast bowler? Don't say both are great. Choose one and give reasons to support that.
