Air filters are all much of a muchness really. I am of the belief that a good panel setup will do a lot better than a pod, however I don't fully discount the abilities of the pods as a lot of people who are running Turbos etc use them, and they are even part of some Jim Mock DEV kits.
The main issue with ANY air filter/induction system, regardless of shape or whether it's a snorkel and box setup or not, is what air is it going to be getting in there? The goal should always be to get the coldest air possible in there, thus some guys who have pods fitted (Rollin is one I can think of), have made up heatshields to stop the hot air from the bay being sucked right back into the engine. How you shield and set it all up is up to you.
However, if you dont want to be stuffing around with making heatshields etc, the standard snorkel+box setup is usually sufficient. I know some guys have added extra piping to their airbox to get more air in there (I think Casper has run a pipe from his airbox to behind his headlight so it gets air from there, he said it made a bit of difference), but essentially how you go about it is up to you, and you can't really expect 'x result from x setup'. The results on every car will be different.
But yeah, as long as you're aiming (and getting) as much cold air in there as possible, you should be right.
Just my 2c, apologies if I've gotten anything wrong.

You can setup the pod inside the EF airbox with a $10 part from holden. The au snorkel also does wonders.
