Verdict
The clearest difference is review sentiment: NVH at 81% against DC Connect+'s 33%. NVH also leads on update cadence (weekly vs every 13 months) and chart position (#196 vs unranked). DC Connect+'s advantage is price (Free vs $99.99) and rating (4.5 vs 4.2). On ratings volume, ads, in-app purchases and device support there is nothing between them.
