Your cable company will probably supply you a modem router. If you are forced to rent it then definitely buy a pure modem.. whatever is on the compatible list with your cable company. Then buy yourself a router. That is much better combo than standard handout stuff.
Asus high end routers are very good.. anything from RT-AC68U and above. The firmware is pretty common feature wise between them.. with newer AX models now coming out like RT-AX88U. The new wireless standard will give you no improvement over AC with older clients and even most new ones do not yet support AX so buying the most expensive to ready for latest standards is not recommended.
Synology RT2600AC is also popular as Extreme replacement.
I would expect 3-4year lifespan for most domestic routers so spending heaps on AX or Game models is really not worth it. Middle of the road. $200-400 is fine.
Most other brands I have tried, TP-Link, Netgear, Linksys, Tenda, etc have very basic firmware. And it is updated rarely if at all. They work OK for most people with very simple needs. And are usually a bit cheaper for same specs cf the Asus or Synology.
A lot of people are now moving to better grade gear like Ubiquiti. It is more expensive by say 50% but is semi-pro and more reliable with better lifespan. It does require a lot of learning to be useful. So for most people I would say Asus.
Note that not all routers play well with Apple protocols, Bonjour, Airplay etc. Asus and Synology have worked well for me. As does Ubiquiti. I have run into issues with some of the others.
Also for really good wireless over whole house mesh products are now also available. The routers tend to be very simple but wireless works without needing to run ethernet over the house.
