VyOS for performance but if you don’t use a network device CLI regularly and it’s for home use OPNsense.

OPNsense comes with a lot of pretty sane defaults for a gateway/firewall, VyOS you really do everything from scratch, as it’s more geared towards enterprise or service provider.

VyOS does do well as a gateway/firewall and there is a lot you can install to extend features for stuff like what OPNsense has to the point that I have had 0 things I couldn’t do when I migrated a few years ago.
