Verdict
The clearest difference is rating: Sync at 4.6 against OneControl Auto's 2.7. Sync also leads on review sentiment (17% vs 6%) and ratings volume (4.1K vs 820). OneControl Auto's advantage is in-app purchases (none vs 2). On price, update cadence, ads and device support there is nothing between them.
