Verdict
The clearest difference is rating: U8 at 4.1 against iD Disk's 1.0. U8 also leads on review sentiment (64% vs 50%) and ratings volume (10 vs 1). iD Disk's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence and device support there is nothing between them.
