Superlist's advantage is price (Free vs $299.99) and rating (4.5 vs 4.0). On ads, device support and iOS requirement there is nothing between them.

Superlist is free to download; CASA Space Frame 3D costs $299.99 up front. Superlist sells 15 in-app purchases, starting at $6.00 per month. CASA Space Frame 3D asks for nothing beyond the download.

Superlist holds the better App Store score, 4.5 against 4.0.
