OpenWrt vs Pfsense

For a home user, what advantages and disadvantages does Pfsense offer over OpenWrt?

I use OpenDNS family shield on my OpenWrt router and redirect all port 53 requests to the router. This blocks porn but not on google image searches. Can Pfsense filter google image results? i.e. block porn images from search results? I know this setting is available on Google search itself.

I have an adblock installed on OpenWrt
