Verdict
The clearest difference is review sentiment: U4 at 50% against ISIC's 20%. U4 also leads on monetization model (ad-supported vs free with in-app purchases). ISIC's advantage is update cadence (every 5 weeks vs every 3 months). On price, ads, in-app purchases and device support there is nothing between them.
