Verdict
The clearest difference is in-app purchases: SuguMemo at none against BatterySync's 2. SuguMemo also leads on update cadence (every 3 days vs every 2 months). BatterySync's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On price and ads there is nothing between them.
