Verdict
The clearest difference is rating: TesDisplay at 2.4 against Testars Tool's 1.0. TesDisplay also leads on review sentiment (24% vs 0%) and ratings volume (46 vs 2). Testars Tool's advantage is in-app purchases (none vs 1) and update cadence (weekly vs every 2 months). On price, ads and device support there is nothing between them.
