Short answer: the Soundcore Liberty 5 Pro. Both are rated 3.2/5 for sound quality (#955 and #954 of 1291 in-ear headphones), and the Soundcore Liberty 5 Pro costs $169.99 against $199 for the NF Acous NM25, so with nothing between them on sound quality, price settles it.
The case for the NF Acous NM25: A single dynamic driver earphone with a bright, detailed character that suits V-shaped and neutral listeners, with a low end that stays within 6 dB of target down to 20 Hz. The catch: Treble runs about 6 dB above target from 6 to 16 kHz, peaking 12.3 dB near 11.2 kHz in the median of 7 hobbyist measurements on squig.link, so cymbals, hi-hats and sibilance can sound hot and fatiguing at higher volume.
What the Soundcore Liberty 5 Pro does well: These true wireless earbuds have bass about 2 to 3 dB above target and extend flat to 20 Hz, giving a warm, punchy sound that suits bassy and warm listeners. Watch for: Hobbyist measurements give it a Harman preference score of 64.2 with 2.5 dB of deviation, a fairly colored tuning.
Buy the Soundcore Liberty 5 Pro. Both are rated the same for sound quality, and it costs $29.01 less than the NF Acous NM25.
