The clearest difference is rating: Sort'n Fill at 4.6 against Stack'n Merge's 3.0. Sort'n Fill also leads on ratings volume (10K vs 2). Stack'n Merge's advantage is in-app purchases (none vs 13) and update cadence (daily vs fortnightly). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Sort'n Fill sells 13 one-off in-app purchases. Stack'n Merge asks for nothing beyond the download.

Sort'n Fill holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Sort'n Fill has 10K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 29% of Sort'n Fill's written reviews are positive against 50% of Stack'n Merge's, so the app with the better star average is not the one people write more warmly about.
