Short answer: the Topping M62. It ranks #1 of 17 audio interfaces by measured performance, rated 4.4/5, at $249. The MOTU M2 ranks #6, rated 3.8/5, at $199.95, $49.05 cheaper, which does not close the gap in measured performance.
The Topping M62 is the better-sounding option. Audio Science Review measured 113 dB SINAD, so playback is clean for nearly all listening, and the maker rates the headphone output at 500 mW into 32 ohms, enough for most headphones including many planar magnetic models. The tradeoff: There are no balanced monitor outputs, and the only headphone jack is a 3.5 mm socket, so studio monitors and 6.35 mm plugs need adapters.
Why pick the MOTU M2: Audio Science Review measured 111 dB SINAD from its ESS Sabre32 Ultra DAC, clean for nearly all listening. Watch for: MOTU doesn’t publish a 32 ohm headphone power figure, and Audio Science Review judged the headphone amplifier barely adequate on power and the recording converter only adequate.
Buy the Topping M62. It is rated higher, and saving $49.05 with the MOTU M2 does not make up for the sound-quality gap.

Topping M62: $249.00 Amazon $249.00 eBay
Pros: Audio Science Review measured 113 dB SINAD, so playback is clean for nearly all listening, and the maker rates the headphone output at 500 mW into 32 ohms, enough for most headphones including many planar magnetic models. It runs on a battery and takes USB-C, Bluetooth, two 6.35 mm inputs, a 3.5 mm mic and an AUX input, with parametric EQ on each input and a 10-band output EQ. It rates higher than the MOTU M4 while costing less.
Cons: There are no balanced monitor outputs, and the only headphone jack is a 3.5 mm socket, so studio monitors and 6.35 mm plugs need adapters. The Topping E2x2 offers XLR outputs and similar measured cleanliness for less.
