Verdict: The Rheem Performance Platinum 50 Gallon for most users due to its current status and 50-gallon storage capacity, while the discontinued Rinnai RUR199IN provides 199000 BTU continuous flow and ENERGY STAR qualification but carries availability risks. Rheem supports natural gas or electric with low NOx and electronic ignition features; Rinnai is Wi-Fi capable and condensing. The Rheem is the stronger pick unless unlimited on-demand flow is the top priority.
