I moved over to opnsense yesterday. Just built my config in a vm. Exported. Installed the firewall and imported and setup the interfaces.
It should do all of that and seems to have a few nice features to boot. As well as a much steadier release cycle. And a security audit feature built in to tell you if the updates available will patch vulns. Which I found neat
Nice, and thanks for the heads up on your experience. I was actually just looking into comparisons of them today, because I wanted to know what the major differences were, if any. I came across this[1], which while not extremely recent, it within the last year.
Everything looks pretty good for opnsense IMO based on that. The only thing that gave me pause was the note about (unsubstantiated) reports of VLAN problems in opnsense that have supposedly been broken for a while. We make heavy use of VLANs, so that would be problematic, but it could be fixed by now or never have been the longstanding problem reported for all I know, I haven't gotten to that point because I'm not planning on anything in the immediate term that requires it.
I haven’t had any problems so far with them. (I run about 5 vlans at home).
Keep in mind I’m using intel nics (igb driver), promiscuous mode on. They seem the same as others.
The major things I’ve had to muck with.
1) NUT seems bugged. I can’t get it talking via usb as a stand-alone at all. Though I can see the APC UPS via usbconfig. Even when I just pointed it at my nut server I’m seem TTY broadcasts on the ssh session that its dropping snd reconnecting.
2) vpn configs carried over but assumptions made in PFsense had to be input in opnsense. Such as outbound nat on my full tunnel (I run manual nat). And firewall rules have to be put in, generally with the vpn cidr scope at the source address.
3) suricata is definately less....chatty than my snort config on pfsense. Again assumptions in pfsense have to be put in manually (such as specifying your external IP to $HOME in advanced). Also the new policies filters/rules doesn’t seem well documented though it’s brand new as of 21. I’m thinking et pro has less false positives than my old snort options. I’m also still in IDS mode, haven’t started dropping. Their appid implementation seems broken though.
4) php73 seems to freak out here and there. Webui can be crashy, especially big operations like hitting download for suricata rule sets.
5) traffic shaper is definately a little different. Though for me less complex and better. But I haven’t really dug in. I have seem to drops on a specific rtsp stream cross vlan. Hoping sharing rules can fix it.
Overall I like it. It’s a nice improvement despite the bugs.

Example, the version i built is on 21.1: https://imgur.com/a/2X2UBJQ
