That's not really a fair comparison, since any software packet filter on that class of hardware will be slow.

If you need layer 2 or stateless layer 3 filtering at hardware speeds, Mikrotik makes 10G switches that can do it for under $200. Mikrotik APs also support port and WiFi isolation which is enough security for most home networks (e.g. isolating an IOT VLAN).

Mikrotik's "fastpath" stateful connection tracking feature is also fast in my experience; not fully wire speed but good enough for untrusted devices that you want to be fast, like a Fire stick or game console or similar.
