Short answer: the ART 715-A MK5 for most PA use, the MFX-15MC only for stage-monitor or short-throw fill duty with external amplification already in place. These rank #29 and #30 out of 76 15-inch powered PA speakers, priced at $3,170.67 and $649.
The MFX-15MC is a passive coaxial monitor with the strongest measured result of any coaxial monitor here. Medium-quality vendor data returns a 5.01 ideal-subwoofer preference score with 67Hz measured extension, and the coaxial 15-inch design gives compact 60° x 40° coverage with a claimed 135dB peak with recommended amplification. Its own cons are explicit: it’s not self-powered, requiring an external amplifier and running passive or externally bi-amplified, less convenient than every conventional powered cabinet here, and the narrow pattern is aimed primarily at stage-monitor and short-throw fill use rather than wide-audience main duty.
The ART 715-A MK5 is a self-powered, subwoofer-paired main. It offers 130dB claimed output and FiRPHASE processing, extending the well-regarded ART 712-A MK5’s simple design to a 15-inch woofer for deeper reach. Its own cons note the local low-quality manufacturer data has no computed preference score, making its measured tonal position uncertain, and the smaller compression-driver assembly offers less vocal headroom than the ART 735-A MK5.
Buy the ART 715-A MK5 for a self-powered PA main you can run without external amplification.
Buy the MFX-15MC if you need a coaxial stage monitor or short-throw fill and already run external amplification and DSP.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
