Fire orb or Atck orb?

How much more of a difference is me using a fire orb with Sobin ,and using an atck one with Sobin? Like is the difference a huge one?

I am trying to decide what to craft a fire or atck orb. Ik there are some more AE members coming along so I am also worried Sobin is gonna get kicked out in the future. But if the difference is huge than I can craft the fire one
