The internal switches on “routers” can be quite poor at port-to-port traffic handling, particularly multicast. Certainly true historically. Say 5 to 10 years ago. Is it still? Don’t know.
Also, cheap home switches can have their own issues. But at least, if you have your own home network hardware (and possibly your own secondary router) then when it comes time to change your ISP and get a new router or Modem, it does make it a lot easier.
