If you have a router that works and security is not an issue and you don't have the appetite to invest the time then stick with what you have.

Pros

Your router will after 3-5 years from release (not purchase) is likely to not be supported. Pfsense updates a couple of times a years and has been going for a while.

At least with Asus if you want some of their pretty charts you have to "leak" your data to Trendscan otherwise that feature won't be available to you. I can see this becoming the norm for the other vendors.

Most routers do not support vlans.

You can run "many" (I don't know the limit) OpenVPN Clients and Servers, many routers do not support OpenVPN those that do will be limited in the number of clients and servers it will run.

If you use a paid for VPN service you may need to set it up on a second router to be certain traffic is routed to the VPN for the network. pfsense will easily support the VPN service on an OpenVPN client on its own vlan.
