Verdict
The clearest difference is in-app purchases: Sensory Abstract#3 at none against OgdenSpine's 4. Sensory Abstract#3 also leads on iOS requirement (16.4 vs 18.6). OgdenSpine's advantage is update cadence (fortnightly vs every 63 months). On price, ads and device support there is nothing between them.
