Quick straw poll...

I like OpenWrt a lot. My ISP supplied modem/router was hopeless as the ISP had reserved port 443 for its own admin control of the devices they supply! No, really, they actually did that and you couldn't undo it. So I bought an old BT Home Hub 5 VDSL2 modem/router for very little and installed OpenWrt. It gives me 100% reliability and lets me apply reasonable firewall rules and do sane port mapping and port forwarding so I can run a few services from home. It's very nice to have a router which runs wireguard, so I can always connect to my LAN and use my home server's services as though I was there. I know many people will be doing all kinds of stuff with OpenWrt but I just needed a modem/router which works like you'd hope it would, which it turns out is about as common as the holy grail in the world of ISP supplied hardware. For non-expert home users projects like OpenWrt and Pi-Hole are a godsend.
