What firewall do you use and trust?

[iAwake]

Hello! This is my first post here on this forum. I am using Windows Firewall on all of my devices protected with F-Secure Safe (F-Secure does not offer firewall protection and it relies on WF). I am also using AVG IS on some of my PCs and it offers Firewall protection. Eset's firewall is decent but I stopped using Eset as it is very expensive for me.
