Yes, in that survey. The reality is that the speed differences between 
the different 5G providers are very small, see 
<https://www.tomsguide.com/features/5g-vs-4g>, but the differences 
between LTE speeds were more significant.

OTOH, the geographic coverage differences between the three U.S. 
carriers are very large indeed, as every survey and study has clearly shown.

You can see the enormous differences by looking at the comparison maps:

You can also read the Rootmetrics report on "US State of the Mobile 
Union 1H 2021; Carrier performance at national, state, and metro levels"

The bottom line is that the geographic coverage differences are very 
large, especially when you leave densely populated areas. Even in urban 
areas like the Bay Area, where I live, you can see the large differences 
in coverage when you go just a short distance away from the urban areas.

One area we spend a lot of time in is the Santa Cruz mountains and you 
can see the vast coverage differences, and just how much more coverage 
you get on AT&T and Verizon, versus on T-Mobile, see

of the Sierra Nevada, where there also are significant coverage 
differences, see <https://i.imgur.com/jPmiGtR.png>.
