Best solo dungeon build?

HELLO COMMUNITY I wanted to ask you, what do you think is the best build for dungeon-only, taking into account a 4.4 weapon and a T8 set

I tried the Phantom and I'm not sure, it didn't convince me. I've seen Shadow Caller and I'm not convinced either.

But I've seen the longbow and to my surprise it can be done in 6-7 minutes (1 meal, 4 dungeons, 2 floors). Are there any other weapons/builds you recommend that take the same amount of time or less?
