Verdict
The clearest difference is ads: Morphos at none against Synonym Stack's shown. Morphos also leads on iOS requirement (15.6 vs 17.0). Synonym Stack's advantage is update cadence (every 3 weeks vs every 10 months) and review sentiment (100% vs 82%). On price, in-app purchases, monetization model and device support there is nothing between them.
