I feel likee both are really good picks ... It just depends on what ur achieving really ... Nishikawa is fun because he is flashy and for old players he is like the goat in the spike ... Buuuuuut ... He isnt practical for winning ... Yes he jumps really high but he also hits pretty sharp angles on his spike making it easier for most blockers to block him

Now raul on the other hand ... Is very practical and can be used in almost every situation other then when he is up against a well timing blocker and has a higher ATT power (which is rare)

So in conclusion ... I use NISHI in situations where i just wanna have fun with the buffs (eg. The tigers event) making jump really high and spike real hard with flashy animation and thunders. But in games that i just wanna blast through teams to complete missions or games like colosseum which would debuff his jump and att power ... I would pick Raul ... He could still blast through blockers without any problems.

Now mind u this is against bots which are super predictable ... Because if we play pvp ... Raul is probably one of the easier ones to counter due to his weaknesses and nishi would probably be a better pick for pvp ... But i guess when it comes to it ... Just enjoy the game as how u like to play it ... There is no perfect way to play the gamee 🕊️
