Verdict
The clearest difference is rating: Slyder at 4.5 against Selvy PenScript's 3.6. Slyder also leads on update cadence (every 10 days vs monthly) and ratings volume (1.6K vs 120). Selvy PenScript's advantage is in-app purchases (none vs 12) and iOS requirement (8.0 vs 16.0). On price, review sentiment, ads and device support there is nothing between them.
