Verdict

The call

The clearest difference is ads: RepeatDuck at none against 百词斩's shown. RepeatDuck also leads on rating (5.0 vs 4.8). 百词斩's advantage is ratings volume (9K vs 1) and update cadence (fortnightly vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.
