Verdict
The clearest difference is rating: Notesnook at 4.7 against Collabora Office's 3.3. Notesnook also leads on review sentiment (78% vs 41%) and update cadence (weekly vs every 2 months). Collabora Office's advantage is in-app purchases (none vs 20). On price, ads, device support and iOS requirement there is nothing between them.
