I found the Companion app easy to navigate and use. Other prescription hearing aid companies offer more in-depth health features, but there is still plenty of opportunity to customize settings from your mobile device. The HearingFitness component is also a nice feature for those who like to actively track their progress.
Sony's Hearing Control app includes good features and allows your to further personalize CRE-C20 with their on-ear hearing assessment. One downside though is that the hearing aids and app communicate with sound cues from your phone. I find this method of wireless communication less reliable that Bluetooth, and it overall makes the pairing process more complicated.
Oticon Zeal were extremely comfortable and lightweight in my ears. In general, hearing care providers can make numerous physical changes to prescription hearing aids like Zeal to improve comfort.
CRE-C20 are good comfortable once you find the best tip for your ears. They are not overly plugging though it can take some time to get used to having a hearing aid so deep in your ear canal.

CRE-C20 are surprisingly small and sit mostly invisible in your ears. The style works well and was originally designed as an "instant-fit" prescription hearing aid from Signia.

The Sony CRE-C20 offers moderate value relative to its $999 price point, with several higher-scoring alternatives available at similar or lower prices.
Zeal are easy to use and adjust with the Oticon Companion app. I had no issues making adjustments while testing them.
CRE-C20's smaller size and method of wireless communication make it more difficult to manage than many other hearing aids. However, Sony has improved upon the design as CRE-C20 now uses internal rechargeable batteries, as opposed to disposable ones. It is a unique offering with many pros but be sure to consider this against your needs and abilities.
Prescription hearing aids like Zeal are fit by hearing care providers so you should receive quality care. The Oticon Companion app also opens the possibility for remote programming and virtual follow-up appointments.
Sony does not offer great support with their hearing aids. You are limited to phone and email based technical assistance which is a downside to many OTC products.
