Verdict
The clearest difference is price: spacedesk at Free against Twomon SE's $9.99. spacedesk also leads on rating (4.7 vs 4.0) and update cadence (every 3 weeks vs every 6 months). Twomon SE's advantage is in-app purchases (none vs 11) and review sentiment (85% vs 71%). On ads there is nothing between them.
