Verdict
The clearest difference is review sentiment: Space Defender at 100% against Spaceship Rocket Simulator's 0%. Space Defender also leads on ads (none vs shown) and update cadence (daily vs every 6 weeks). Spaceship Rocket Simulator's advantage is in-app purchases (none vs 1) and iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
