There appear to be a few YouTube videos comparing these two interfaces (actually the 204HD more than the 202HD, but that shouldn’t be any difference). If you haven’t seen any of these, give them a google. I used “how does the behringer umc202hd compare to the motu m2.”
The only thing I think may be relevant is that I heard that the Behringers may have a weaker output signal than expected. I can’t confirm nor deny this personally.
