Verdict

The call

The clearest difference is in-app purchases: Phosphor Emulator at none against ArcEmu's 10. Phosphor Emulator also leads on update cadence (every 3 days vs every 2 weeks). ArcEmu's advantage is ratings volume (1.3K vs 39) and rating (4.9 vs 4.6). On price, ads, device support and iOS requirement there is nothing between them.
