Short answer: a tie on sound quality. Both are rated 3.6/5 (#746 and #742 of 1291 in-ear headphones) at nearly the same price ($22.99 vs $23), so choose on features and fit.
Why pick the AGASound AGA One: A broadly balanced tuning with a preference score of 69 against the Harman target. Watch for: An uneven response, 2.1 dB standard deviation from target.
The case for the iBasso Jr. Gelato: A single dynamic IEM in a stainless steel shell. Watch for: Sub-bass falls about 3.4 dB short at 30 Hz.
Buy the AGASound AGA One or the iBasso Jr. Gelato on features: they are rated the same for sound quality at close to the same price.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
