Unifi is great

Got 3 sites now all managed in one place

I use UniFi for switches and AP, it doesn’t make sense to use something else for gateway, not even the AmpliFi or EdgeRouter product lines. Single pane of smooth glass to manage everything in one place.

Pfsense got some bad blood for doing shady things to make opnsense look bad. Beyond that, Unifi management is easy to set up and less to mess around with and has auto updates if you keep the contoller up and enable it.when I used opnsense and pfsense even, I left it out of date since I wasn't following for updates, and it was a lot more micro managing than I wanted to on a router even though I knew how.

Got time? Want to learn networking? Want more advanced configs? Go wih opnsense/pfsense

Want to have time to do other things? Unifi

Edit: also not sure if pfsense or opnsense does, but unifi has the best rated local integration with controller and home assistant. Easy reboot of PoE devices, monitoring PoE power usage, transmission rates on ports, automation, enabling scheduling WiFi networks or security settings, presence detection by tracking peoples phones connected to the WiFi, etc.

Ruckus APs and Opnsense have been solidly reliable for me for 5y now. No random fucking with unifi bugs (like having my WPA enterprise SSID punting users out onto the management vlan at random instead of the Kerberos assigned VLAN for that user, thanks unifi) and fantastic wireless coverage has me completely satisfied with my infra choices. Also, Ruckus unleashed handles controller duty on the primary AP rather than requiring a management container, that's also a plus.

Ubiquiti has had outages in the past that meant you couldn't manage the equipment right in front of you.

Even discounting the potential security implications of that kind of management, the rage I would feel in that situation is enough that I while my AP is nice, works great, I will never use any of their gateways.

I'm using a 2.5g protectli with OPNSense now, and it's easy to manage, and all local.

Pfsense all the way. I have a couple of unifi 10GB switches downstream acting as dumb switches. I’m happy.

I use pfSense on a Protectli vault with a Unifi Pro switch and Unifi AP. it all works great. I prefer pfSense over the full unified UDM gateway, pfSense appears to offer more features and plugins. but I haven't played with the unifi gateway myself. also a lot cheaper

I used pFSense for years until Netgate took over. That is when I switched to OPNSense (maybe 2019/2020, don't remember excatly). Since then, I've had OPNSense (runnign on a Lenovo m720q tiny) and Unifi (APs and UNVR) for wireless and cameras. I like this setup, it gives me all the advanced routing features I want and have become accustomed. I'm sure Unifi routers are good for most use cases and would have the added convenience of one interface for everything. However, I've not been impressed with price to performance ratios for their past offerings (ie. the routing capabilities of OPNsense with an i5 CPU and option for swapping a quad port 1gbe nic to a dual port 10gbe nic) is hard to compete against. That said, the UDM-SE looks interesting.

I have a UDMPro I got 2 years ago i believe. Had a netgate SG3100 with PFsense for 6 years before that until the sg3100 hardware and support went EOL. Was happy with both but went with the UDMPro to be able to support the camera systems and was comparable to another netgate device but was about $100 cheaper with a $50 promo. I mostly use it locally and via app at some points.

Just within the last 2 years the UDMs finally got equivalent features to my setup with PFsense. Wireguard and per port GeoIP restrictions and logging were the most used features on my PFsense that from videos and forums didn't seem like it was added to unifi stuff until just the last couple years.
