Verdict
The clearest difference is price: Space UI at Free against White Nightmare's $1.99. Space UI also leads on ads (none vs shown) and update cadence (every 2 months vs every 18 months). White Nightmare's advantage is iOS requirement (15.6 vs 26.0). On in-app purchases and device support there is nothing between them.
