Verdict
The clearest difference is price: Phosphor Emulator at Free against ArcEmu's $1.99. Phosphor Emulator also leads on update cadence (every 3 days vs every 2 weeks). ArcEmu's advantage is ratings volume (1.3K vs 31) and review sentiment (95% vs 80%). On ads, in-app purchases and device support there is nothing between them.
