Verdict
The clearest difference is in-app purchases: Cube Fillz! at none against Negentropy's 7. Cube Fillz! also leads on update cadence (every 5 weeks vs every 21 months) and iOS requirement (13.0 vs 15.0). Negentropy's advantage is ads (none vs shown). On price and device support there is nothing between them.
