Verdict
The clearest difference is in-app purchases: Horizone Web Server at none against xxter's 4. Horizone Web Server also leads on iOS requirement (10.0 vs 12.0). xxter's advantage is update cadence (every 3 months vs every 11 months). On price, ads and device support there is nothing between them.
