Idle Mastermind's advantage is ratings volume (440 vs 30). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Idle Mastermind sells 12 one-off in-app purchases and Rando'Knights sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
