Math and Science Tutor's advantage is ratings volume (920 vs 30) and rating (4.8 vs 4.6). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Math and Science Tutor sells 1 in-app purchase, starting at $19.99 per month and I Aced Calculus AP Prep sells 3 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
