Verdict
The clearest difference is ads: KeyBoltz at none against PDF Reader's shown. KeyBoltz also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.4). PDF Reader's advantage is update cadence (every 4 days vs fortnightly). On price and in-app purchases there is nothing between them.
