I used to run PFSense ( pretty much the same as Opensense ) and really liked it but moved over to Ubiquity in the last year or so. Here’s my 2 cents…

Go with Ubiquity if you want a single unified interface for managing all your devices. You’ll have “soft vendor lock in”, their kit will work just fine with a mix of hardware but it’s best if everything is Ubiquity

Go with Opensense if you want complete flexibility in the kit you’re using. I feel likeI had more fine grained control with PFSense than I do with Ubiquity but I think that’s a symptom of how the UI/UX rather than the features

You can do the same stuff with both options. I’m very happy with my Ubiquity set up, I don’t see myself changing anything anytime soon
