Verdict

The call

OP.TCG and Mugi both sit at 4.6 stars, but that hides the real split: 82% of OP.TCG's written reviews are positive against 44% of Mugi's. OP.TCG also leads on ads (none vs shown) and iOS requirement (15.3 vs 18.5). Mugi's advantage is monetization model (free vs freemium) and update cadence (every 4 days vs every 3 weeks). On price, rating, ratings volume and in-app purchases there is nothing between them.
