Verdict

The call

The clearest difference is price: Dubnote at Free against Voice Builder's $4.99. Dubnote also leads on update cadence (every 5 days vs fortnightly). Voice Builder's advantage is in-app purchases (none vs 6) and chart position (#185 vs unranked). On rating, ratings volume, ads and device support there is nothing between them.
