The nice thing about the newer 2 is 6ghz, for people in highly congested areas. I live on an acre and pick up tons of 2.4ghz, some 5ghz. I can't imagine how bad it would be in a modern tract home development, or worse, a large apartment complex.
When I was still at university, just walking out of my studio appartement and closing the door would already drop my 5GHz signal a good bit. Open the door, much better.
Of course the -real- benefit to upgrading early is that you'll likely have the 6ghz space to yourself for a couple years.
Unfortunately, this also means I'm competing with nearly a hundred different APs in the apartment alone - of which many broadcast in both 2.4GHz and 5GHz - to the point that my Macbook less than a meter away from the router still takes a hot minute to automatically find the AP unless I manually select it.
