Problem is that your hearing perception gamut is subjective. Your hearing conditioning is subjective. Whether you like Jazz or Heavy Metal is subjective. Your loudness perception is subjective. Your tonal bias is subjective.
The concept that brand X in somebody else’s opinion is the best, is moot in your case. Hence trial periods.
If you look at some of the most profligate wearer postings on here, you’ll see that their own opinion of their hearing/hearing aids changes through the habituation process. So, look at all the points above in the context if it being a dynamic issue. Can you understand why ‘recommendations’ are going to be loose at best?
