I agree, I have been using linux for over a year now using nothing but IPtables. I have yet to have a single port sniffer, or even attempted hack get through my system.
If you want a little more control over your IPtables you could install firestarter on your linux box. This will give you a little more of a GUI control look to the iptables.
