Verdict
The clearest difference is in-app purchases: PDF Reader at none against Days Left's 1. PDF Reader also leads on review sentiment (100% vs 78%). Days Left's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 114 months). On price and device support there is nothing between them.
