Verdict
The clearest difference is ads: BlueID SDK at none against ScreenPenguin's shown. BlueID SDK also leads on iOS requirement (10.0 vs 15.0). ScreenPenguin's advantage is update cadence (every 3 days vs every 2 months). On price, in-app purchases and device support there is nothing between them.
