Verdict
The clearest difference is in-app purchases: Userscripts at none against O's 25. Userscripts also leads on ads (none vs shown) and review sentiment (78% vs 63%). O's advantage is ratings volume (8.6K vs 181) and rating (4.5 vs 4.3). On price, update cadence and device support there is nothing between them.

Both are free to download. O sells 23 one-off in-app purchases. Userscripts asks for nothing beyond the download.
O holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: O has 8.6K ratings behind it against 181, so its average is the more settled of the two. Written reviews complicate that: 78% of Userscripts's written reviews are positive against 63% of O's, so the app with the better star average is not the one people write more warmly about.
Userscripts ships an update monthly, O every 2 weeks. The most recent releases landed on October 13, 2026 and October 14, 2026 respectively.
