Verdict

On the 2 of 12 dimensions that carry measured values today, radon differs — 17110 is Zone 1, 19103 is Zone 3 (lower is less predicted potential); 2025 median air quality is Good in both (AQI 44 vs 50). zipradar names no overall winner: the other 10 dimensions are not populated yet, and these two are county-level indicators rather than address-level readings.
