That's weird, reliable low latency audio is one of the few things where I still find the Mac to be pretty solid. I've got a 2015 15" and I've used several times a 2018 13", on both Mojave and Catalina and I have to say that it outperforms my 2015 (it can easily manage a 32 buffer with some plugins loaded, while my 15" starts to struggle under 64). This was using Reaper with an Apple USB-A to USB-C adapter and a UMC204HD interface
