Verdict
The clearest difference is rating: SpecScan VIN Decoder at 5.0 against Fuel's 3.1. SpecScan VIN Decoder also leads on update cadence (every 5 days vs every 10 months). Fuel's advantage is in-app purchases (none vs 3) and ratings volume (33 vs 1). On price, ads, monetization model and device support there is nothing between them.
