I think you'll find the majority verdict would be for a panel filter. The STI one is highly rated.
Induction kits have a number of problems including causing the MAF sensor to misread, deteriorate, and eventually break, and also the fact that you have now moved the air source out of the wing where it gets a good supply of cold air into the engine bay where the air is warm. All of these things mentioned are not desirable and may well lead to detonation problems, if bad enough it will blow your engine.
Induction kits have there uses in really high power builds but then generally the ECU is changed to a type that does not use a MAF sensor thus alleviating those problems. It is then also a good idea to shield the induction kit from the rest of the engine bay and provide a cold air feed.

Panel filter gernerally considered more 'safe' as give marginally cooler intake temp, Also quieter and cheaper and less likely to cause MAF sensor problems.
Induction Kits undoubtedly flow better, make a nice noise, give marginally higher intake temps and reputedly are more likely to give MAF sensor issues (this is a constant and ongoing debate BTW) and of course costs more.
Just depends what you want - although there is an anomaly that may be worth considering - here it is:
