Verdict
The clearest difference is in-app purchases: 碁楽 Goraku at none against Go Challenger's 5. 碁楽 Goraku also leads on ads (none vs shown). Go Challenger's advantage is update cadence (every 5 weeks vs every 3 months) and iOS requirement (13.0 vs 17.0). On price and device support there is nothing between them.
