Verdict
The clearest difference is review sentiment: PermuLogic at 100% against Sudoku's 50%. PermuLogic also leads on in-app purchases (none vs 3) and ads (none vs shown). Sudoku's advantage is ratings volume (659 vs 2) and iOS requirement (13.0 vs 17.0). On price and device support there is nothing between them.
