Verdict
The clearest difference is rating: O'Reilly at 4.7 against DevTo's 1.0. O'Reilly also leads on update cadence (every 2 weeks vs every 29 months) and ratings volume (34K vs 1). DevTo's advantage is monetization model (free vs subscription). On price, ads, in-app purchases and device support there is nothing between them.
