  This paper presents studies of the performance of water-based liquid
scintillator in both 1-kt and 50-kt detectors. Performance is evaluated in
comparison to both pure water Cherenkov detectors and a nominal model for pure
scintillator detectors. Performance metrics include energy, vertex, and angular
resolution, along with a metric for ability to separate the Cherenkov from the
scintillation signal, as being representative of various particle
identification capabilities that depend on the Cherenkov / scintillation ratio.
We also modify the time profile of scintillation light to study the same
performance metrics as a function of rise and decay time. We go on to interpret
these results in terms of their impact on certain physics goals, such as solar
neutrinos and the search for Majorana neutrinos. This work supports and
validates previous results, and the assumptions made therein, by using a more
complete detector model and full reconstruction. We confirm that a
high-coverage, 50-kt detector would be capable of better than 10 (1)\%
precision on the CNO neutrino flux with a WbLS (pure LS) target in 5 years of
data taking. A 1-kt LS detector, with a conservative 50\% fiducial volume of
500~t, can achieve a better than 5\% detection. Using the liquid scintillator
model, we find a sensitivity into the normal hierarchy region for Majorana
neutrinos, with half life sensitivity of $T^{0\nu\beta\beta}_{1/2} > 1.4 \times
10^{28}$ years at 90\% CL for 10 years of data taking with a Te-loaded target.
