Verdict

The call

The clearest difference is in-app purchases: PDF Reader at none against Translator Keyboard's 14. PDF Reader also leads on chart position (#35 vs #131) and iOS requirement (13.0 vs 15.6). Translator Keyboard's advantage is ads (none vs shown) and ratings volume (21K vs 3.3K). On price, rating, review sentiment and update cadence there is nothing between them.
