Verdict
The clearest difference is ads: DriveRack PA2 Control at none against Feedback Trainer's shown. DriveRack PA2 Control also leads on iOS requirement (12.0 vs 16.6). Feedback Trainer's advantage is update cadence (every 2 weeks vs every 8 months). On price, in-app purchases and device support there is nothing between them.
