Verdict

The call

The clearest difference is rating: KORG Module at 4.6 against GO's 2.7. KORG Module also leads on review sentiment (52% vs 20%) and ratings volume (787 vs 3). GO's advantage is in-app purchases (none vs 10) and update cadence (every 2 weeks vs monthly). On price, ads and device support there is nothing between them.
