First: it’s Mb/s
And actually there’s a lot of difference between what is reported and the real speeds.
I for example get reported 1733 Mb/s on both sides (XPS13 with Intel 9260 towards Linksys WRT32X), but iperf only reaches 450 Mb/s. Others report a stable 1000 Mb/s on the same devices, so there seems to be still other factors that influence the connection (probably Wi-Fi driver on my windows laptop).
Also keep in mind, that the distance is of great importance and if there are obstacles between your access point and your mobile device.
And last - in my eyes the naked speed is irrelevant. What counts is how many devices the access point can serve (here a clear plus for wave2!) and the coverage of your home. It depends on your home’s architecture, it’s really strategic where you place your access points. 802.11AC’s high throughput is senseless if you get those speeds only in one room and the rest of your flat/house has no access. So there is a need to also use Wi-Fi cards in the 2,4 GHz spectrum which allow are significantly better coverage.
My advice: be a little bit patient and wait for 2,4 GHz 802.11ax cards which will combine high throughput (ca 1200 Mb/s) and coverage! [if you are living in a more rural area, unfortunately the 2,4 GHz band is too crowded in the urban areas ).
