Verdict
The clearest difference is rating: Circle Run at 5.0 against Planet simulation's 3.9. Circle Run also leads on review sentiment (100% vs 74%). Planet simulation's advantage is in-app purchases (none vs 1) and update cadence (every 8 months vs every 137 months). On price and iOS requirement there is nothing between them.
