Verdict
The clearest difference is review sentiment: Vision Engage at 72% against DXJ's 14%. Vision Engage also leads on rating (4.8 vs 2.3) and ratings volume (6.3K vs 55). DXJ's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.
