Verdict
The clearest difference is price: Slitherlink at Free against Fillomino Infinite's $0.99. Slitherlink also leads on rating (4.8 vs 3.6) and ratings volume (461 vs 5). Fillomino Infinite's advantage is in-app purchases (none vs 13) and review sentiment (100% vs 89%). On ads and device support there is nothing between them.

Slitherlink is free to download; Fillomino Infinite costs $0.99 up front. Slitherlink sells 13 one-off in-app purchases. Fillomino Infinite asks for nothing beyond the download.
Slitherlink holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: Slitherlink has 461 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 89% of Slitherlink's written reviews are positive against 100% of Fillomino Infinite's, so the app with the better star average is not the one people write more warmly about.
