OpenWrt enthusiast's choice; good value, but lacks 6GHz.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
WRT54G/GL running DD-WRT. Started buying them in 2004? 2005? and installed them in all of my family's houses and had them VPN back to a server at my house. Ran perfectly before I replaced them with Ubiquiti gear about 10 years ago. Sure, by that time they were getting a bit long in the tooth, but they still ran and ran well.
Same. I had updated the firmware to one of the open source ones and it just keep running. It wasn't until I got "too many" newer devices in the house that overloaded it (random devices would drop off with no warning) that I needed to replace it. I relaxed it with a beefy ASUS, but that thing died after like 18 months. Since then, I use access points and pass everything through an actual firewall... No more consumer grade "routers" for me.
ASUS RT-N66U. Bought it to replace my WRT54G that failed 13 or 14 years ago and still am using it.
WRT54G with DD-WRT and a cantenna. Despite what the haters say, cantennas made a measurable difference if setup correctly.
Same, ddwrt then tomato
Yes, but only for nostalgia sake. I flashed mine to DD-WRT before I stopped using it. I could probably still use it. My speed needs aren't much.
Asus RT-AC66U B1. It was the minimum model I could find that would USB tether a cellular hotspot or phone for the WAN source. I hardly ever do the cellular tethering, but I wanted that capability. I also run a USB hard disk on the USB as a ghetto NAS. It wasn't the latest model when I got it, but It has been the rock solid best router I ever owned. I can't remember the last time I had to restart it. I don't like the UI, but I haven't looked at it in years. I got FIOS a few months ago. The stupid FIOS router USB does not support cellular tethering or hard disk storage, only USB power supply. I have the Asus WAN port connected to one of the FIOS router LAN ports. Otherwise my needs are not much. I don't need mesh. The house isn't that big.
