Verdict
The clearest difference is in-app purchases: python3$ at none against UI Tracer's 2. python3$ also leads on chart position (#74 vs unranked) and ratings volume (23 vs 4). UI Tracer's advantage is update cadence (every 2 days vs weekly) and rating (5.0 vs 4.7). On price and ads there is nothing between them.
