Verdict

The call

The clearest difference is rating: Liner at 4.4 against Bluebook's 1.7. Liner also leads on review sentiment (39% vs 14%) and ratings volume (1.4K vs 27). Bluebook's advantage is in-app purchases (none vs 10) and iOS requirement (13.0 vs 16.4). On price, update cadence, ads and device support there is nothing between them.
