The clearest difference is rating: Unity AAC at 5.0 against Avaz AAC's 4.5. Unity AAC also leads on update cadence (every 6 weeks vs every 5 months). Avaz AAC's advantage is ratings volume (74 vs 1) and monetization model (free with in-app purchases vs paid). On price, ads, in-app purchases and device support there is nothing between them.

Avaz AAC costs $299.99 and Unity AAC $299.99 up front. Neither carries in-app purchases, so what you see is what you pay.
