That depends. 5G at low speeds allows for much longer range which I like when I travel in a very remote area. 5G also allows for much faster speeds at very low range, so if you are in a very crowded city you will notice. For most people most of the time they are not in such a remote area that only 5G towers can be affordably built, nor are is data so congested that they would notice the shared bandwidth limitations.

About once a year I do travel through those remote areas where my 4g phone never got service, but as soon as I got 5g I had service (there are still areas so remote I don't get 5g service either)
