Verdict

The call

The clearest difference is price: Comms at Free against Aviation Study Guide's $29.99. Comms also leads on rating (4.2 vs 3.6) and update cadence (every 4 days vs every 5 weeks). Aviation Study Guide's advantage is in-app purchases (none vs 12) and review sentiment (62% vs 36%). On ads and device support there is nothing between them.
