The clearest difference is rating: Jayson at 4.5 against Device Info Tool's 4.0. Jayson also leads on review sentiment (81% vs 50%) and ratings volume (425 vs 4). Device Info Tool's advantage is in-app purchases (none vs 1) and iOS requirement (16.2 vs 26.0). On price, update cadence, ads and chart position there is nothing between them.

Both are free to download. Jayson sells 1 one-off in-app purchase. Device Info Tool asks for nothing beyond the download.
