Verdict

The call

The clearest difference is ratings volume: Days at 12K against My Bookshelf's 171. Days also leads on review sentiment (74% vs 57%) and update cadence (every 5 days vs fortnightly). My Bookshelf's advantage is iOS requirement (12.1 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.
