Short answer: the NF Audio NA3. It ranks #725 of 1291 in-ear headphones by sound quality, rated 3.6/5, at $69.99; the JBL Live 300TWS ranks #788, rated 3.5/5, at $69.99. Close enough in price that the sound-quality gap is the deciding factor.
What the NF Audio NA3 does well: A single dynamic IEM with a dual cavity design. The catch: A 2.33 dB spread from the target shows peaks and dips that better tuned sets avoid.
Why pick the JBL Live 300TWS: It uses 1 x 5.6mm dynamic with an easy 16 ohm load. Watch for: Its 2.30 dB spread is less even than the best measured sets.
Buy the NF Audio NA3. It is rated higher for sound quality than the JBL Live 300TWS at the same price, so only choose the other one for a particular feature it does better.
