Verdict

The call

The clearest difference is update cadence: AWS at every 9 days against Mechanical Engineering Lab's monthly. AWS also leads on iOS requirement (8.0 vs 17.0). Mechanical Engineering Lab's advantage is price ($12.99 vs $15.99). On ads, in-app purchases and device support there is nothing between them.
