Mochizuki is a polyphonic synthesizer built around four oscillators and two filters. The four oscillators can be mixed in parallel or connected in series to create more complex sounds. Each oscillator can also be configured as one of four types: AM, FM, Noise, or Resonator. Most parameters can be modulated using a wide range of modulation sources, including envelopes, LFOs, step sequencers, macros, and per-note expression such as pitch bend and slide. Signals from each oscillator and filter can be routed individually, with independent control over their destinations and levels. This makes it possible to create flexible and complex signal routings, combining conventional serial connections with parallel paths and multiple signal paths.

Verdict
The clearest difference is in-app purchases: WindSynth 16 at none against Mochizuki's 5. Mochizuki's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 6 weeks). On price and device support there is nothing between them.
