Verdict
The clearest difference is review sentiment: CPU at 82% against CPU X's 39%. CPU also leads on rating (5.0 vs 4.4) and price ($0.99 vs $2.99). CPU X's advantage is ratings volume (309 vs 1) and update cadence (every 10 days vs every 6 weeks). On ads and in-app purchases there is nothing between them.
