Verdict

The call

The clearest difference is price: EQ at Free against F's $2.99. EQ also leads on update cadence (every 2 weeks vs every 8 months) and review sentiment (90% vs 78%). F's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.8). On ratings volume, ads and device support there is nothing between them.
