I would suggest one of the differences between analog and digital is that the analog versions are more limited in what they can do with compression. It is now common to amplify soft sounds more than normal sounds and loud sounds less than normal. This is used because many of us lose our hearing more at low levels of sound than at high levels. Our hearing response to volume or amplitude is no long linear or normal. Compression if properly set up can restore some of that linearity.
That said, one of the prescriptive options to set up a digital hearing aid is the 1/3 gain rule that was used with older analog HA’s, because that was all they were capable of. It is linear and amplifies all levels of sound by a constant amount. Someone that has used that prescription potentially gets used to it, and prefers it.
One thing you could do with a modern digital hearing aid is request that a demo pair be set up with three programs adjust to different prescriptive formulas using the Real Ear Measurement. I would suggest trying most common standard one which is NAL-NL2, the less common but modern DSL v5, and the 1/3 gain. The specific HA manufacturer may have a proprietary method which could be worth a try two. So if the hearing aid can handle 4 different programs then take them home and try them all to see what you like.
