Verdict
The clearest difference is in-app purchases: Gleaner Highlights Widget at none against System Guard's 1. Gleaner Highlights Widget also leads on ads (none vs shown). System Guard's advantage is update cadence (weekly vs every 6 months) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
