Verdict
The clearest difference is rating: iStick Ultra at 5.0 against uDisk's 4.3. iStick Ultra also leads on in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 2 months). uDisk's advantage is ratings volume (248 vs 1) and iOS requirement (11.0 vs 15.0). On price, ads and device support there is nothing between them.
