The F205 clamp multimeter is a good replacement for these 2 models because it offers measurement of the W, var, VA and var power values for single and balanced three-phase configurations, phase rotation direction testing and THD measurement, as well as the revolutionary TrueInrush function for measuring overcurrents.
The F205 clamp can be used for measurements with currents up to 600 A. On higher-powered installations, you should choose the F405 or F605 which offer the same functions for currents up to 1,000 A and 2,000 A, respectively.
