Verdict

The call

The clearest difference is in-app purchases: 3D ZANZO at none against ボイボTTS's 1. 3D ZANZO also leads on ads (none vs shown) and iOS requirement (12.0 vs 16.0). ボイボTTS's advantage is update cadence (every 3 weeks vs every 3 months). On price and device support there is nothing between them.
