Verdict
The clearest difference is rating: 打印机 at 5.0 against UBackup's 2.0. 打印机 also leads on review sentiment (25% vs 9%) and iOS requirement (13.0 vs 15.0). UBackup's advantage is in-app purchases (none vs 3) and ratings volume (82 vs 1). On price, update cadence, ads and device support there is nothing between them.
