Verdict

The call

The clearest difference is price: SoundViz at Free against X's $3.99. SoundViz also leads on update cadence (every 3 weeks vs every 4 months). X's advantage is ads (none vs shown) and iOS requirement (9.0 vs 17.0). On in-app purchases and device support there is nothing between them.
