Why people look past pfSense
Nothing on the record flags a reason to move. pfSense has a free tier. People still switch over fit and workflow, and those are not things a catalogue entry can measure, which is what the comparisons below are for.

Cheaper ways to solve the same problem
What you would be giving up
pfSense is most often brought in for a home user or small business wanting a free, fully-featured firewall on commodity hardware with no licence cost, a business wanting an integrated firewall appliance with vendor support, typically buying a netgate appliance bundled with pfsense plus, a team wanting to evaluate advanced features like real-time threat intelligence before committing to netgate hardware or a plus migration, an organisation replacing an expensive commercial firewall with an open source alternative while retaining the option to add commercial support later. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.
Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.
If pfSense is broadly right and the question is cost, the pfSense pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Networking category lists everything the directory holds, and best networking tools ranks them.
pfSense runs on linux. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.
