Question about what account I should focus on

Made a new account for step ups since I didn't have many 5☆ on my original account and not many ways to get orbs without farming for raid characters and maxing them. So I made a new account and got the following. The one with 4 6 stars is my original and the other is new, any thoughts? Should I stick with my old one or go hard on my new one?
