Verdict
The clearest difference is price: SCUM Time at Free against Jupiter Attack's $1.99. SCUM Time also leads on rating (5.0 vs 4.5) and update cadence (every 6 days vs every 2 months). Jupiter Attack's advantage is in-app purchases (none vs 2) and ratings volume (383 vs 1). On ads and device support there is nothing between them.
