Verdict

The call

The clearest difference is review sentiment: Ultra Boost at 100% against TopGuru's 29%. Ultra Boost also leads on rating (5.0 vs 3.5) and in-app purchases (none vs 30). TopGuru's advantage is ratings volume (413 vs 4) and update cadence (every 3 weeks vs every 2 months). On price, ads and device support there is nothing between them.
