Verdict
The clearest difference is in-app purchases: C310 Performance at none against Small Clock's 1. C310 Performance also leads on ads (none vs shown) and update cadence (every 5 days vs every 3 months). Small Clock's advantage is iOS requirement (13.0 vs 16.0). On price and device support there is nothing between them.
