Verdict
The clearest difference is in-app purchases: Nonogram at none against Circuits!'s 5. Nonogram also leads on review sentiment (91% vs 60%) and ratings volume (621 vs 10). Circuits!'s advantage is ads (none vs shown) and update cadence (every 10 days vs every 4 months). On price, rating, monetization model and device support there is nothing between them.
