In the US (and more specifically, the USGS), QRev discharge computation algorithms are the ‘standard’ for all moving boat ADCP discharge computations. It is a requirement in the USGS. This is one of the reasons that QRev was written. Many (most?) other agencies in the US track what the USGS does and therefore, I suspect that most would be using QRev, but I have no proof of that. I am sure that Dave Mueller can provide even more information than this.
