As you can see, the Uni-T UT70A is the most affordable multimeter of the three. It also has a True RMS display, which means it can accurately measure AC waveforms of any shape. However, it has a lower accuracy than the Mastech MS8208 and the Fluke 115.

The Mastech MS8208 is slightly more expensive than the Uni-T UT70A, but it has a higher accuracy. It also has a few additional features, such as a diode test function and a continuity buzzer.

The Fluke 115 is the most expensive multimeter of the three. It has the highest accuracy and the most features. It also has a NCV function, which allows you to detect live wires without touching them.

Ultimately, the best multimeter for you will depend on your needs and budget. If you are looking for an affordable multimeter with True RMS and auto ranging, the Uni-T UT70A is a good option. If you need a multimeter with higher accuracy and more features, the Mastech MS8208 or the Fluke 115 are better choices.
