I believe you are using the presonus quantum 2 thunderbolt unit? What are your thoughts regarding latency, etc. How about compared to a usb unit? I am installing a thunderbolt adapter on my pc which is backward compatible to thunderbolt 2 with an adapter cable I believe. There are some pretty good prices on the quantum 2 right now I see. I also like the Apollo solo thunderbolt 3. Just thinking about interface options.
I don't have the Q2 up and running yet, but the Thunderbolt cable should have a slight edge over the USB.
I'll give you more appropriate feedback once I've logged some time with it.
