Verdict
The clearest difference is rating: Mobile Master at 4.5 against CPU Info's 2.5. Mobile Master also leads on update cadence (every 6 days vs every 3 months) and ratings volume (1.2K vs 2). CPU Info's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support there is nothing between them.
