Verdict
The clearest difference is in-app purchases: Planet simulation at none against Atom Fusion's 1. Planet simulation also leads on ratings volume (164 vs 6). Atom Fusion's advantage is ads (none vs shown) and update cadence (every 5 days vs every 7 months). On price and device support there is nothing between them.
