Verdict
The clearest difference is rating: Auto Agent at 4.9 against Fuelpak FP3's 4.0. Auto Agent also leads on review sentiment (75% vs 36%) and ratings volume (42K vs 156). Fuelpak FP3's advantage is in-app purchases (none vs 6) and update cadence (monthly vs every 3 months). On price, ads and device support there is nothing between them.
