Verdict
The clearest difference is rating: ReverseVoice at 5.0 against Sixfast's 4.4. ReverseVoice also leads on in-app purchases (none vs 28) and update cadence (every 2 days vs every 3 weeks). Sixfast's advantage is ratings volume (223 vs 6). On price, review sentiment, ads and device support there is nothing between them.
