Short answer: the Harman Kardon Luna. It ranks #26 of 175 medium speakers by sound quality (rated 4.0/5) at $290.99 and is still sold new; the Soundcore Motion 100 ranks #45 (rated 3.7/5) and is discontinued, so it is only an option used.
The Harman Kardon Luna is the deeper-bass choice. The sound is fairly balanced apart from the boosted bass. Its bass reaches about 57Hz before falling 10dB, against 65Hz for the Soundcore Motion 100. The catch: Boosted bass, and less detailed than higher-ranked speakers.
The Soundcore Motion 100 is the lighter pick. At 1.3 lbs (575 g) it weighs much less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It supports LDAC Bluetooth, which the Harman Kardon Luna lacks. It has an adjustable EQ, which the Harman Kardon Luna lacks. Watch for: Not very deep bass, slight distortion.
Buy the Harman Kardon Luna. It is rated higher for sound quality and still sold new, while the Soundcore Motion 100 is discontinued.
