Pcmag article: "Another member of the PCMag staff also reported that on low-band connections in rural areas, the Pixel was actually able to maintain a connection that the S21 Ultra dropped."
"It’s certainly clear that, on paper, the Samsung modem the Pixel 6 and Pixel 6 Pro use just aren’t up to the gold standard that Qualcomm offers. However, as we noted in our review, signal strength and speeds in day-to-day use don’t really tell the same story. Without comparing speeds and strength side-by-side, it’s harder to see the disparity.
It appears without PCMAG actually stating it in clear English; these tests were not performed by the same person, while in the exact same provider area, with the phones side-by-side.
Whereas the other tests WERE done side-by-side in the exact same provider areas. And I believe the key word will be PROVIDER areas. Since LTE coverage has always varied, sometimes daily, from one location to another, and it will also vary for 5G coverage. The majority will never notice drops or rises in signal strength since it will not affect a phone call, and in most cases no noticeable change in surfing.
I am not saying which phone is better, since I am still in the air about which phone to purchase; just saying if I was to pick which article I would, personally, put more credence in it was the actual side-by-side comparison.
