That does not match my prejudices :) For my particular use case, sound
quality and to some degree noise floor are secondary considerations
compared to standard compliance, reliability, latency.  While I am
personally more of an audio quality buff with a focus on recording, if
the U-Phoria supposedly checks the boxes I need, that would be the
pricing on the cake.

I need to ask the exact model of Behringer that my one orchestra
colleague got.  That one's performance (regarding latency/dropouts) did
not really appear to improve upon my stone-age Tascam US-122L brick
(which you can throw basically in any bag without worrying about
anything breaking off).  Maybe something related to drivers.
