Wordfence VS Ninja Firewall
I can be very short in my answer, there have been many reviews about both those firewalls.
The good thing about Wordfence is it user interface, loved by many. The bad thing is that is uses a lot of database tables and is resource intensive especially when live monitoring is on.
Ninja firewall is very lightweight and fast, it does what it should do; and does a good job. You can read a benchmark here: WordPress brute-force attack detection plugins comparison
They are both good plugins, the big difference is that Ninja Firewall is not resource intensive and will not affect your pagespeed or server resources neither to many database tables. That is why we choose Ninja Firewall for our clients.
