Verdict
The clearest difference is ads: M2E at none against speed Tool's shown. M2E also leads on monetization model (free vs ad-supported). speed Tool's advantage is update cadence (every 2 weeks vs every 69 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
