Cellular RF Performance – Does anyone have an iPhone 7 and a Galaxy S8?

I am very interested on both AT&T and Verizon if anyone both of these phones: (posting the question in each forum)
1. iPhone7/iPhone7 Plus *and*
2. Samsung Galaxy S8

One peculiar thing in this article [1] (the iPhone 7 intel vs. qualcomm) is the last graph, e.g., band 4 comparison, the Galaxy S7 edge is almost 2x the performance in throughput vs. the iPhone 7 Plus.

Has anyone put both phones side by side and checked the signal level from the tower?
Additionally, has anyone run speed tests to the same speedtest.net server and compared the performance?
