Best firewall

[cool11]

I know that mac os x is the best os around but internet has many threats.
So I want to use a good firewall.

I use littlesnitch. It seems to be a good applications.

I read about netbarrier and other firewalls.

Which one do you prefer most of you and why?
I want to use the best of them, in order to have the best protection for my system.

What do you mean by "best?" The ipfw implementation in OS X, particularly in conjunction with NAT, is more than enough in terms of safety as long as you can keep the ports closed, and you don't run untrusted software from inside the network. Higher-power firewalls usually differ in their ability to more carefully tweak your opening of ports to the outside world and in their ability to monitor traffic originating from inside the LAN (as littlesnitch and zonealarms do). But I don't think they're particularly less vulnerable to an external attack on a set of closed ports than a NAT is.
