Verdict
The clearest difference is price: Units at Free against eBookSort's $0.99. Units also leads on ratings volume (150 vs 3) and iOS requirement (13.5 vs 17.0). eBookSort's advantage is in-app purchases (none vs 3) and ads (none vs shown). On rating, update cadence and device support there is nothing between them.
