Verdict
The clearest difference is update cadence: iDevTools at every 3 months against Preview App's every 13 months. iDevTools also leads on chart position (#117 vs unranked) and price ($0.99 vs $1.99). Preview App's advantage is iOS requirement (15.6 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
