Verdict

The call

The clearest difference is ads: Unity at none against Light's shown. Unity also leads on monetization model (free vs ad-supported) and iOS requirement (8.0 vs 12.0). Light's advantage is update cadence (every 4 months vs every 28 months). On price, review sentiment, in-app purchases and device support there is nothing between them.
