The clearest difference is in-app purchases: 51See at none against Lock Screen Wallpaper's 1. 51See also leads on ads (none vs shown) and iOS requirement (8.0 vs 15.0). Lock Screen Wallpaper's advantage is update cadence (every 3 days vs every 3 weeks). On price and device support there is nothing between them.
