Verdict
The clearest difference is in-app purchases: Pop Cosmic at none against Millisecond Clock's 3. Pop Cosmic also leads on ads (none vs shown) and update cadence (weekly vs every 6 months). Millisecond Clock's advantage is ratings volume (131 vs 2) and iOS requirement (15.0 vs 18.6). On price and device support there is nothing between them.
