Verdict

The call

The clearest difference is rating: Sudoku at 4.7 against HAL 9000's 4.0. Sudoku also leads on update cadence (monthly vs every 36 months) and ratings volume (59K vs 2). HAL 9000's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price and device support there is nothing between them.
