Verdict
The clearest difference is price: MusiWiki at Free against 421Grid's $1.99. MusiWiki also leads on update cadence (every 10 days vs every 3 months) and iOS requirement (12.0 vs 18.0). 421Grid's advantage is in-app purchases (none vs 1). On ads and device support there is nothing between them.
