Verdict
The clearest difference is in-app purchases: ScreenPenguin at none against SoloWatermark's 2. ScreenPenguin also leads on update cadence (every 3 days vs weekly) and device support (3 vs 1). SoloWatermark's advantage is ads (none vs shown). On price and iOS requirement there is nothing between them.
