Verdict
The clearest difference is rating: Spaceflight Simulator at 4.8 against Genius Mechanic's 3.7. Spaceflight Simulator also leads on ads (none vs shown) and update cadence (every 9 days vs every 6 months). On price, in-app purchases, monetization model and device support there is nothing between them.
