Verdict
The clearest difference is rating: VAG Coding at 4.2 against Diag's 3.1. Diag's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
VAG Coding holds the better App Store score, 4.2 against 3.1. Both are backed by a comparable volume of ratings — 14 and 5 respectively. Written reviews complicate that: 40% of Diag's written reviews are positive against 33% of VAG Coding's, so the app with the better star average is not the one people write more warmly about.
