| Summary:
The advent of gadolinium-loaded Super-Kamiokande (SK-Gd) and of the
soon-to-start JUNO liquid scintillator detector marks a substantial improvement
in the global sensitivity for the Diffuse Supernova Neutrino Background (DSNB).
The present article reviews the detector properties most relevant for the DSNB
searches in both experiments and estimates the expected signal and background
levels. Based on these inputs, we evaluate the sensitivity of both experiments
individually and combined. Using a simplified statistical approach, we find
that both SK-Gd and JUNO have the potential to reach $>$3$sigma$ evidence of
the DSNB signal within 10 years of measurement. The combined results are likely
to enable a $5sigma$ discovery of the DSNB signal within the next decade.
