Verdict

The call

The clearest difference is rating: Sudoku at 5.0 against iBuilder's 2.2. Sudoku also leads on in-app purchases (none vs 1) and update cadence (every 4 weeks vs every 29 months). iBuilder's advantage is ads (none vs shown) and ratings volume (12 vs 2). On price and device support there is nothing between them.
