I have both Avid HDX and UA Apollo 8 interfaces. The Mojave update really trashed ProTools on the laptop that I was using… it just doesn’t recognize the interfaces any more. I, of course, didn’t upgrade the desktop Mac, So the studio is cool… but watch out for potential issues before you upgrade. The downgrade is a huge pain as well.
As to the OP, cheap interfaces and mixers always have downsides, but can be OK. Generally look for a mixer with a bunch of direct outs, the Midas live consoles are very good and versatile, but not small, and not really inexpensive. I’ve not had really good luck with the Focusrite interfaces… others have. I tried a Presonus for a remote solution, but had noise issues, and clock issues with it… Presonus told me that it was a known issue with Mac laptops, but weren’t going to fix it, or arrange any type of refund or upgrade. Not the type of customer service that I could recommend.
MOTU stuff has always been solid, just watch out for the latest OS upgrades to see if your gear stays compatible.
I have been running various DAWs since the 80’s… Nowadays, when I get a studio machine working, it never sees the internet again.
*** Update ***
After thrashing for a couple of hours today, I got the laptop to see the interfaces again. The problem was that Mojave changes a bunch of access permissions to the microphone, and all interfaces are considered microphones. Even, or maybe especially, on a previously working machine, you have to manually grant permissions through the privacy settings.
