What exact computer interface (USB 2? 3? ... ), Thunderbolt 2, 3 ... etc are you looking for? you mention USB models you are looking at but you could be giving away a little latency vs thunderbolt.

What IO features do you need? SPDIF? on optical or coax can be present or not at this price range. Same with MIDI... do you need either? Do you want any monitor control features? How important is hardware monitoring to you? if you need to learn to use a hardware mixer software app I would take time to flick through the doc for that.

UAD and Motu also make nice interfaces.

Apogee make nice products but the breakout cable adapter on the Duet would make that a non-starter for me. (ha I see Ben mentioned that as well. Apogee seem to have a blind spot for cable silliness. I dealt with funky cables on their small JAM guitar interfaces... owned several, and they still have not worked that out on their latest JAM Pro... they should have been just used a USB-C port on the device).
