Verdict
The clearest difference is rating: PyLeap at 5.0 against BlueGrays's 4.4. PyLeap also leads on in-app purchases (none vs 6) and ads (none vs shown). BlueGrays's advantage is update cadence (every 6 days vs every 5 months) and ratings volume (11 vs 2). On price and device support there is nothing between them.
