Verdict

The call

The clearest difference is monetization model: Text to Speech Reader at free with in-app purchases against Text to Speech PDF Reader's subscription. Text to Speech Reader also leads on review sentiment (74% vs 46%). Text to Speech PDF Reader's advantage is rating (4.5 vs 4.3) and update cadence (every 10 days vs every 3 weeks). On price, ratings volume, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Text to Speech PDF Reader holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 552 and 240 respectively.
