Verdict
The clearest difference is rating: OneArbitrage at 5.0 against Senpi's 3.8. OneArbitrage also leads on update cadence (every 2 days vs every 4 months). Senpi's advantage is monetization model (ad-supported vs subscription). On price, ratings volume, ads and in-app purchases there is nothing between them.
