Based on the lab data, not for most people: the 300 actually scores higher on speech in noise (1.8/5 vs 0.8/5), speech in quiet (4.0/5 vs 3.1/5), and overall SoundScore (4.3/5 vs 3.9/5). The 700's advantages are newer Bluetooth features like Auracast and LE Audio, plus slightly better build quality and app scores, not better core hearing performance.
