I’ve got a MC3+ USB that I use for my main desk, to send out to a mojo mystique evo pro, and receive from a crane song hedd quantum for a desktop mic (yes it’s overkill but I don’t have any other use for it at the moment lol). Great interface overall for bang for the buck, very versatile, and performance can be improved further with the addition of the ref10 which I might consider later on (but don’t really think I can justify it for now)
