Verdict

The call

The clearest difference is ads: STEMadium at none against Idle Space Manager's shown. STEMadium also leads on rating (5.0 vs 4.8). Idle Space Manager's advantage is update cadence (every 2 months vs every 27 months) and ratings volume (1.7K vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
