Undulib's advantage is ratings volume (29 vs 2) and iOS requirement (9.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Book Cast Player holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Undulib has 29 ratings behind it against 2, so its average is the more settled of the two.
