Verdict
The clearest difference is ads: Slitherlink at none against Nurikabe's shown. Slitherlink also leads on ratings volume (461 vs 8) and iOS requirement (15.6 vs 17.0). Nurikabe's advantage is update cadence (every 5 days vs every 4 months) and review sentiment (100% vs 89%). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Slitherlink sells 10 one-off in-app purchases and Nurikabe sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Nurikabe holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Slitherlink has 461 ratings behind it against 8, so its average is the more settled of the two.
