Need Advice (Twin Sword/Bow User)

Hi guys it's my first post here but since i have a question i'm doing it along with a introduction
. I'm Tatsumi and i'm a Twin Swords/Bow user. I recently finished Kyoto and won a Ougi with the Gacha Ticket so i'm not sure wheter i should put it on my Bow or Twin Swords, the Ougi is set 3 and the skills are:
For Twin Swords: Thunder Beast
For Bow: Water Cannon
Worth noticing that my next twin swords will probably be Chidori which increase thunder damage, even so what do you guys think its best?
