Verdict

The call

The clearest difference is review sentiment: RevDue at 100% against G SHELL's 19%. RevDue also leads on rating (5.0 vs 2.4) and update cadence (daily vs every 2 weeks). G SHELL's advantage is monetization model (free vs free with in-app purchases) and ratings volume (7 vs 1). On price, ads, in-app purchases and device support there is nothing between them.
