Even looking at the "official trial data" you can see that many people arent pleased with the results.
The use of the phrase "somewhat-much better" means that it includes everyone who indicated the implant was even the teenist better than their current HA (which may or may not have been any good - aka, miracle ear, songbird etc).
The fact that there are only three choices, rather than a scale of 1 to 10 is an indicator itself that most people who choose "somewhat-much better" likely choose that option not becuase it was a significant improvement, rather it was marginally better.
And yes, I trust real world users opinions much more than company propaganda aimed at promoting and selling their product.
Since you prefer anecdotal evidence to clinical studies, see the attached audiogram from a friend of mine who had her Esteem activated today. The bottom line is unaided, the middle (black) line is with her hearing aid, and the top "S" line is her hearing now, with the Esteem on at a relatively low volume setting (they start you out low because the new sounds can be overwhelming). The highlighted line is "normal" hearing.
When you consider that it eliminates feedback, occlusion and distortion issues, and that users overwhelmingly prefer the quality of sound from the Esteem vs hearing aids, I think it's pretty clear that this device is pretty revolutionary for HOH people. The tech is in it's infancy, and will only improve.
