We perform a comparative analysis of nucleosynthesis yields from binaryneutron star (BNS) mergers, black hole-neutron star (BHNS) mergers, andcore-collapse supernovae (CCSNe) with the goal of determining which are themost dominant sources of r-process enrichment observed in stars. We find thatBNS and BHNS binaries may eject similar mass distributions of robust r-processnuclei post merger (up to 3rd peak and actinides, $A\sim200-240$), afteraccounting for the volumetric event rates. Magnetorotational (MR) CCSNe likelyundergo a weak r-process (up to $A\sim140$) and contribute to the production oflight element primary process (LEPP) nuclei, whereas typical thermal,neutrino-driven CCSNe only synthesize up to 1st r-process peak nuclei($A\sim80-90$). We also find that the upper limit to the rate of MR CCSNe is$\lesssim1\%$ the rate of typical thermal CCSNe; if the rate was higher, thenweak r-process nuclei would be overproduced. Although the largest uncertaintyis from the volumetric event rate, the prospects are encouraging for confirmingthese rates in the next few years with upcoming surveys. Using a simple modelto estimate the resulting kilonova light curve from mergers and our set offiducial merger parameters, we predict that $\sim7$ BNS and $\sim2$ BHNS eventswill be detectable per year by the Vera C. Rubin Observatory (LSST), with priorgravitational wave (GW) triggers.
