Verdict
The clearest difference is rating: Defender's Attack at 5.0 against S.T.G.'s 4.0. Defender's Attack also leads on update cadence (every 2 months vs every 5 months). S.T.G.'s advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.
