Buddha Is good no doubt, and having it will certainly help a lot in both Second Sea and Third sea and First Sea. but every other fruit is better in their own way as i am light fruit
And have defeated many magmas etc. but in my opinion if youre an First Sea player don't pick magma or ice unless you have a ton of time or money as they take lots of time to reach, so i think light is best fruit as it is the fastest and does good damage
