Short answer: the Topping M62. It ranks #1 of 17 audio interfaces by measured performance, rated 4.4/5, at $249. The Solid State Logic SSL 2 MKII ranks #14, rated 2.9/5, at $199.99, $49.01 cheaper, which does not close the gap in measured performance.
The Topping M62 is the better-sounding choice. 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. Watch for: 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.
What the Solid State Logic SSL 2 MKII does well: It runs entirely on USB C bus power while providing two mic, line and instrument inputs, balanced monitor outputs and two headphone jacks. The catch: At 94 dB SINAD, sensitive in ear monitors may reveal hiss or noise, and Audio Science Review found distortion in both the DAC and ADC rising with level and frequency, so it did not recommend it.
Buy the Topping M62. It is rated higher, and saving $49.01 with the Solid State Logic SSL 2 MKII does not make up for the sound-quality gap.

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.

Pros: It runs entirely on USB C bus power while providing two mic, line and instrument inputs, balanced monitor outputs and two headphone jacks. Audio Science Review measured 94 dB SINAD, fine for most headphones, and liked its appearance and ergonomics.
Cons: At 94 dB SINAD, sensitive in ear monitors may reveal hiss or noise, and Audio Science Review found distortion in both the DAC and ADC rising with level and frequency, so it did not recommend it. SSL doesn’t publish a 32 ohm power figure. The Arturia MiniFuse 2 rates higher for a similar price.
