Let's compare...
Reason for win:
Isine has a total of 60% bonuses in critical areas (Offense, Defense, MDefense), while Thor has a total of 30% bonuses situated in only the two offenses (It is not efficient to split offenses)

Thor has stronger special attacks, but Isine has more special attacks, granting a better probability to use them. Better to use special attacks than basic

Isine wins
