Verdict
The clearest difference is rating: BattleBrain at 5.0 against Sidius Nova's 4.4. BattleBrain also leads on in-app purchases (none vs 3) and iOS requirement (9.0 vs 14.0). Sidius Nova's advantage is update cadence (every 3 months vs every 28 months) and ratings volume (49 vs 2). On price, ads and device support there is nothing between them.
