English Dub
The greatest thing about english dub of digimon adventure 02, in my opinion, is that the voices of characters are suited for their age and quality (I really mean it)
For example someone who is considered reliable or smart has a voice that gives you the feeling of that quality. Like Davis, his voice is really the reflection of his growth throught the story. At the beggining he is stubborn and naive,but gaining experience he becomes more calmer and the actor dubs him more crefully and considerebly.
That difference can be seen on the original digidestined. There is a big difference between the first time they camed in the digital world and in adventure 02 when they take their challenges calmly, believing that anything is possible they are less disturbed by the new challenges.
In the Japanese version the voices are original, so the performers are giving extra of their capabilities.
The english version seems to have actors that really put themselves in giving life to these characters by their honest and deep preformance. (Check Tai crying in Adventure 01)
