Verdict
The clearest difference is price: Star Grab at Free against Duet Game's $2.99. Star Grab also leads on in-app purchases (none vs 2). Duet Game's advantage is update cadence (every 3 months vs every 18 months) and ratings volume (2.1K vs 3). On rating, ads, device support and iOS requirement there is nothing between them.
