Verdict
The clearest difference is rating: B&J at 5.0 against 100%'s 4.5. 100%'s advantage is ads (none vs shown) and ratings volume (39 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 100% sells 1 one-off in-app purchase and B&J sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
