I have done some side by side testing comparing a Qualcomm 8+ vs an Xs Max on VZW. The VZW signal at my house is fairly weak band 13. The 8+ did better with band 13. Neither of these lines are anywhere near the deprioritization threshold. They are both on the feb unlimited plan.

Qualcomm 8+

5.67/2.51

5.29/1.34

7.29/1.86

4.52/1.95

2.38/0.82



Xs Max

1.49/0.32

2.48/0.70

3.16/0.92

2.98/0.16

4.67/0.30



Here are some results where I can pick up some weak band 2/4 signals. These results are more mixed. The 8+ did better on the downlink. The Xs Max on the uplink. We might be seeing benefits of 4x4 MIMO on the Xs Max here.



Qualcomm 8+

58.0/2.47

32.1/2.79

48.3/2.36



Xs Max

35.0/4.39

29.3/3.72

38.7/3.26



I realize that anecdotal data like this isn't conclusive. I don't have a test lab at my disposal.



I'll post some T-mobile tests comparing the Galaxy S9+ (Qualcomm) and iPhone Xs Max later in the week.
