Verdict
The clearest difference is in-app purchases: V3 SOUND CONTROL at none against CoilTrail's 2. V3 SOUND CONTROL also leads on iOS requirement (12.2 vs 15.0). CoilTrail's advantage is update cadence (every 5 days vs every 2 months) and device support (3 vs 1). On price and ads there is nothing between them.
