I don't have a funnel, but I'm going to echo these sentiments on the vortex. I don't like it and highly prefer my standard Egyptian bowls. The shisha just doesn't heat evenly and I don't see how it could unless you stirred it up every once in a while.
Don't get me wrong, I enjoy having it, but with all the hype around here for the small funnel bowl I would definitely choose the funnel.
Edit: Oh and I also believe that a well engineered vortex would beat any funnel bowl, the problem is it isn't shallow enough by a long shot.
