Verdict
The clearest difference is price: EdrawMax at Free against Hydraulic schemes's $0.99. EdrawMax also leads on ratings volume (33 vs 1). Hydraulic schemes's advantage is rating (5.0 vs 3.4) and update cadence (every 2 weeks vs every 6 weeks). On ads, in-app purchases, monetization model and device support there is nothing between them.
