Verdict
The clearest difference is monetization model: Millisecond Clock at free with in-app purchases against Flip clock's subscription. Millisecond Clock also leads on review sentiment (73% vs 57%). Flip clock's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 6 months). On price, rating, in-app purchases and device support there is nothing between them.
