Short answer: the E1DA 9039S. It ranks #2 of 14 usb-c dongle DACs by measured performance, rated 4.4/5, at $139. The TANCHJIM Space ranks #5, rated 4.2/5, at $89.99, $49.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the E1DA 9039S does well: Audio Science Review measured a SINAD of 125 dB, so its noise and distortion are inaudible, even with sensitive in-ears. The catch: Its only headphone output is a 2.5 mm balanced jack, so most headphones need an adapter or a new cable.
Why pick the TANCHJIM Space: Audio Science Review measured 115 dB SINAD, right at the level where noise and distortion become inaudible, so this dongle is effectively transparent. The tradeoff: It rates below the FiiO KA15 for a similar price, and that rival publishes more than twice the power from its balanced output.
Buy the E1DA 9039S. It is rated higher, and the $49.01 you would save on the TANCHJIM Space does not close the gap.

E1DA 9039S: $139.00 Linsoul eBay
Pros: Audio Science Review measured a SINAD of 125 dB, so its noise and distortion are inaudible, even with sensitive in-ears. E1DA rates it at 400 mW into 32 ohms balanced, enough for most headphones from a 10 g USB-C dongle with dual ES9039Q2M chips.
Cons: Its only headphone output is a 2.5 mm balanced jack, so most headphones need an adapter or a new cable. The FiiO KA15 rates higher with more balanced power for less.

TANCHJIM Space: $89.99 HiFiGo eBay
Pros: Audio Science Review measured 115 dB SINAD, right at the level where noise and distortion become inaudible, so this dongle is effectively transparent. A rated 230 mW into 32 ohms drives most headphones, and it offers both a 3.5 mm jack and a 4.4 mm balanced output with dual CS43131 DAC chips. Button volume control lets you adjust level on the dongle itself.
Cons: It rates below the FiiO KA15 for a similar price, and that rival publishes more than twice the power from its balanced output. The TRN Black Pearl rates higher and measured cleaner for much less. The 230 mW figure suits most headphones but leaves little headroom for hard to drive planar magnetic models.
