Verdict
The clearest difference is rating: Device Tester at 4.0 against CPU Info's 2.5. Device Tester also leads on update cadence (weekly vs every 3 months) and ratings volume (245 vs 2). CPU Info's advantage is in-app purchases (none vs 1). On price, ads, device support and iOS requirement there is nothing between them.
