Verdict
The clearest difference is in-app purchases: Zenith at none against Satellite Chasers's 2. Zenith also leads on rating (4.8 vs 4.5). Satellite Chasers's advantage is update cadence (monthly vs every 13 months) and ratings volume (26 vs 5). On price, ads and device support there is nothing between them.
