Your informal comparison is running into problems again because you are conflating two different things: EIRP and RSRP. The former is transmitted power, the latter received power. For regulation purposes, the FCC is concerned with only transmission, not reception. So, all FCC OET published test results are for transmission. We do not routinely get test results for reception -- other than anecdotal reports, such as twospirits' observations.
But the gist of it is this: transmission performance does not necessarily correlate with reception performance -- and vice versa. Compared to a superior transmitter, a poor/average transmitter may exhibit little, if any difference in reception. And the two different devices may perform much the same in strong signal areas. For reference, twospirits had very strong band 25 signal across his tests. However, in weak signal areas, that poor/average transmitter more quickly will run out of power on the uplink. In such cases, downlink reception is irrelevant, and the link will fail, dropping to EV-DO, CDMA1X, roaming service, or no service in more locations.
