Verdict

The call

Vaia and Nerdmask both sit at 4.7 stars, but that hides the real split: 81% of Vaia's written reviews are positive against 29% of Nerdmask's. Vaia also leads on ratings volume (1.6K vs 199). Nerdmask's advantage is update cadence (every 3 days vs weekly) and iOS requirement (15.1 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.
