I like the English voices better than the Japanese voices. But that might also be affected by how I feel the localization has improved the script substantially. The dialogue is still pretty awful I think, but it's not as offensively cliche, and the dreadful sexual innuendos are toned down. If you don't understand Japanese at all and just like the "sound" of their voices your mileage might vary. P
In a particular scene in florem:
The line where Ringabell says "Its settled. We're going sexy!" for Agnes's costume, the English VA nailed it. I tried listening to the Japanese VA and maybe its because I don't speak Japanese but it just wasn't doing me justice.
