I have a fourth generation I7 with 8gb of ram running pfsense. Its free and you can’t beat it for baked in capabilities. I run pfblocker ng and snort to block ads maleware and useless(to me) telemety that my non linux machines send in regularly. Microsoft, Amazon and others. I also have wiregurad for vpn access to my home. You can also install the ntopng package and get really good realtime information on what is going on on your network. For years I used open wrt but the two don’t really compare. If you had to compare, openwrt is like a geo metro and pfsense is like a sports car.
