We're really dealing with four parameters here. Three are physical/engineering - CO2 intensity (gCO2eq/kWh), surface power density (W/m2), capacity factor (%). One is economic - LCOE ($/kWh).
Nuclear has very good first three but high LCOE.
PV has low LCOE but poor capacity factor and surface power density, similar on-shore wind.
Off-shore wind has slightly better capacity factor but LCOE comparable with nuclear.
