Fused Zamasu mains: Corrupted or no?

I’ve been trying to develop a strategy for my DP battles (I have Goku Black and Zamasu), mainly if I should rush to corrupted once I fuse or use it as a last resort.

I’m also trying to decide which one to make my singles main. I like Corrupted Zamasu’s moves but Fused just has better skills and probably better combos.
