Verdict

The call

The clearest difference is ads: Epicenter at none against ゆれくるコール's shown. Epicenter also leads on review sentiment (80% vs 52%) and update cadence (every 4 days vs every 4 weeks). ゆれくるコール's advantage is rating (4.8 vs 4.4) and iOS requirement (13.0 vs 17.4). On price, in-app purchases and device support there is nothing between them.
