Verdict
The clearest difference is price: Bright Comets at Free against NEOScope's $0.99. Bright Comets also leads on update cadence (every 5 days vs every 7 months) and ratings volume (153 vs 1). NEOScope's advantage is rating (5.0 vs 4.3) and in-app purchases (none vs 1). On ads, device support and iOS requirement there is nothing between them.
