Verdict
The clearest difference is rating: Midpoint at 4.7 against ENA's 1.0. Midpoint also leads on update cadence (every 2 days vs every 3 weeks) and ratings volume (32 vs 3). ENA's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price and device support there is nothing between them.
