There is no best firewall. A very important part of a firewall is being able to set it up properly, if you use Kerio but just open everything then it isn't going to be effective, however Kerio has the capability to be far more effective than an application based firewall such as ZoneAlarm, but again if you're lost when using it how secure will you get it? If there was a true "best" there'd be no choices.
TBH I think any of the firewalls that are free and well known are secure enough. You have to weigh ease of use with protection and performance for your uses and your knowledge level. For instance with Kerio with one rule you could have it block cookies, http referrals and images from your email client so that a spammer won't get a hit when you open his email, you won't have that control with ZoneAlarm, however then you'll also run into issues with the email you do want images inand do want to know it's you when you click on it. The highest level of protection is not always the best.
The chances of getting hacked, really hacked are very slim. buy a cheap NAT router, turn off Windows File Sharing if you're not on a network, and run a simple firewall and chances are you'll never ever be hacked. You don't need the best draconian setup out there to be safe, and if you did run the most draconian setup you would never use your computer because it would suck and you couldn't do anything. Without temporarilly opening ports or changing permissions in windows.
