I have been led to believe that the Windows 10 Firewall is as good as they get and will handle most everything except a Professional Hacker.
I know you're joking but, such platitudes (which are so common www) make no sense because under the hood, 3rd party firewalls use the same filtering platform that built-in Windows firewall does.
The only difference is they are more user friendly and have a shinny look for obvious reason $$
Those who can break windows firewall, don't need much time learn how to break same thing that just has differently looking user interface.
So what would you guys recommend for windows 8.1? Needs to be somewhat easy to use and free if you have any recommendations.
They will all do the same job, behind the scene, so choose which ever feels easy to you.
However how much secure will be depends on rules that you define.
My recommendation is to find firewall that also has some built in rules (so that you don't have to create your own) in addition to easy of use interface.
