Verdict

The call

The clearest difference is rating: Tachimanga at 4.8 against ONE PIECE BASE(EN)'s 3.6. Tachimanga also leads on review sentiment (76% vs 36%) and ratings volume (5.3K vs 37). ONE PIECE BASE(EN)'s advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.
