Verdict

The call

The clearest difference is ads: RedGuard at none against PDF Scanner's shown. RedGuard also leads on ratings volume (681 vs 12) and rating (4.6 vs 4.3). PDF Scanner's advantage is update cadence (every 9 days vs every 17 months). On price, in-app purchases, monetization model and device support there is nothing between them.
