Is Riverside.fm worth the cost over just recording on Zoom for a new podcast?

I am launching a podcast where I interview guests remotely and I am trying to decide between using Zoom for recording and paying for a dedicated tool like Riverside.fm. Right now I record Zoom calls and the audio quality is serviceable but I do notice compression artefacts and the occasional audio dropout that I have to edit around. A friend who produces podcasts professionally told me Riverside would make a noticeable difference but I want to understand exactly why before I start paying for another subscription.

The thing I understand about Riverside is that it records locally on each person's device rather than relying on the internet connection for the audio, which is supposed to eliminate the quality degradation you get from a compressed video call. But I want to know how much of a practical difference that makes in reality. My guests are not in professional recording setups and some of them are on laptops with mediocre built-in microphones, so I am wondering whether the recording quality improvement matters if the source hardware is limiting anyway.

Has anyone switched from Zoom to Riverside and noticed a real improvement in the finished audio? And how do guests find the experience of using it for the first time? If they need to install software or jump through hoops to join I am worried about adding friction to the guest booking process for people who are not particularly tech savvy.
