You do have to be careful with AD running on USB. A dedicated computer running USB should be fine but any contention on the USB bus is not timed and can lead to dropouts. I was running an RME PCIe card for many years in a Mac Pro and it works seamlessly. When I switched to a Mac Studio and tried recording via USB I had some issues that seemed to be related to Bluetooth devices using the USB bus. I use the ethernet connection to a Motu 8D for that recording rig now which is 100% reliable.
RME kit is really decent. I went with Lavry AD/DA years ago and can't hear any difference between the source and recording so I'm not bothered about upgrading but they would be on my list. I have found it useful to have more than 2 i/0 channels though. I would probably look at Prism if I was buying now.
