Verdict

The call

The clearest difference is rating: STS at 5.0 against PDF Reader's 4.0. STS also leads on in-app purchases (none vs 1) and ads (none vs shown). PDF Reader's advantage is update cadence (every 3 weeks vs every 5 months) and ratings volume (41 vs 1). On price, device support and iOS requirement there is nothing between them.
