Verdict
The clearest difference is review sentiment: Circuitry at 96% against DC Circuit Builder's 50%. Circuitry also leads on rating (4.8 vs 2.6) and ratings volume (291 vs 26). DC Circuit Builder's advantage is monetization model (free vs paid) and device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Circuitry holds the better App Store score, 4.8 against 2.6. That said, the two scores are not equally well evidenced: Circuitry has 291 ratings behind it against 26, so its average is the more settled of the two. Written reviews point the same way: 50% of DC Circuit Builder's written reviews are positive against 96% of Circuitry's.
