Verdict
The clearest difference is price: Cereb IoT at Free against USB Mobile Disk's $0.99. Cereb IoT also leads on ads (none vs shown). USB Mobile Disk's advantage is update cadence (every 3 months vs every 12 months). On in-app purchases, device support and iOS requirement there is nothing between them.
