I just noticed a feature in my RT-N66 firmware (John's Fork/Merlin) to set up DNS based filtering. Currently I have WAN DNS server 1 set to my pihole IP and everything else (server 2 and LAN DNS settings) blank. It works well, even on ad heavy sites like msnbc. Would the DNS based filtering be a better choice or should I just leave well-enough alone?

DNS Filter isn't really meant to be an alternative to ad-blocking. It's designed to intercept and redirect DNS requests that are trying to bypass your local DNS configuration. Android devices will often ignore your router-specified DNS and try and go directly to Google's DNS servers.

Essentially the same as pihole but pihole provides its own "blacklist" and is generally used with one of the router LAN or WAN dns servers (user installed). All requests are directed to the pihole which in my case is an RPi B+ connected to a LAN port. Requests on blacklist are simply ignored and never go out. I don't use android devices or google dns servers.

Not really. DNSFilter is a routing function. It forces clients to use a particular DNS server by intercepting their DNS requests and redirecting them to a different destination. Without DNSFilter a client can choose to ignore your Pihole and router settings and use any DNS server it likes.

If you don't have any DNS related issues with your current setup there's probably no reason for you to use DNSFilter.

DNSFilter is categorised under Parental Control. For example, you set your router and Pihole to block access to porn sites. All little johnny has to do is change his laptop's DNS setting to point to 1.1.1.1 or 8.8.8.8 and he can now access those sites. DNSFilter is designed to stop this happening.

In other words, "If it ain't broke..."

I am unaware of anything in my system ignoring the pihole but not having any "droids". I am blissfully ignorant that such even exists.

As I have nothing that will redirect DNS request no compelling reason to change
 
We don use no effin w$.
