Verdict
The clearest difference is ratings volume: Della+ at 433 against Solaris Optics's 6. Della+ also leads on rating (3.6 vs 3.3) and review sentiment (9% vs 0%). Solaris Optics's advantage is update cadence (every 3 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
