Did you notice those improvements or did you just do benchmarks to see if they improved? Not everyone's needs are the same of course, but I have no complaints about my seven year old Nighthawk R7000. Latency-sensitive devices like game consoles are ethernet, phones and laptops are 5GHz, and everything else is 2.4GHz.

I think this is a case of first world country arrogance of putting perfectly working things in the landfill just for the heck of it.

I found it noticeable for anything latency sensitive - conferencing, Terraform/SSH, etc. (losing Google’s iOS hangs was extremely noticeable, of course, but that’s for a different reason)

The key thing to remember is that there’s considerable variability across different peoples’ experience. If you live in a widely spaced suburban house, you probably don’t need to worry about interference the way an apartment dweller does or even someone in a city where the neighbor’s property starts a lot closer. The layout and materials used in your house similarly have a big impact on whether your devices are operating on 5GHz close to a base station or 2.4GHz further away.

Since you have your latency sensitive devices on Ethernet, you probably are fine with an old AP. Cables are definitely better but not everyone has permission or a suitable way to run them (my house built in the 1930s did not include spare conduit).
