It's not an easy question to answer
because tweaked KIS is certainly enough but it's much heavier than my current setup due to application control
if I disable the app control, it's not KIS anymore
moreover, I dislike KIS's firewall because of its inherited settings. When I block explorer.exe connection (Windows explorer) -> I use Windows explorer to open an app which requires internet connection, the app is also blocked because the settings are inherited from windows explorer -> have to manually unblock it -> quite annoying
and when I want to block an app in public network while allow it to connect in Home network, it's impossible. Block in Public = block everything
I think I would choose my current setup although comodo firewall is quite noisy sometimes
