Verdict
The clearest difference is review sentiment: Sudoku² at 81% against mBlock's 34%. Sudoku² also leads on rating (3.9 vs 3.1) and iOS requirement (12.0 vs 15.0). mBlock's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.
