Yeah, this is pretty much my build too. Sukuna's understanding of cursed energy is an insane thing to be able to purchase and that (along with the barest shred of being able to interact positively with human beings) would turn you into Gojo's only peer overnight.
All the rest? Just icing on the cake. I'm not completely sure about what ultimate Shikigami skill would look like, but since Shikigami are just like, artificial curses, it sounds like you'd basically be Geto 2.0 except you'd make the curses yourself.

The only alternative I considered was just going all in on CE as:

>Sukuna's Skill
>Intelligence
>Immense Cursed Energy x 4

Yuta's insane cursed energy is remarked on a lot. Having double would basically just make you into 'ersatz Sukuna', because you'd have a comparable level of CE to the guy and his talent too.
I think it could be argued either way whether that's better than Shikigami however. Afterall we don't get to choose our innate technique so we probably won't be able to immediately fight equally with Sukuna even with this.

I'd prefer the Shikigami build for the sheer utility: doing shit like riding a dragon I made around or whatever sounds awesome. But if forced to choose I might well pick ersatz Sukuna just because of genre savvy. In the world of JJK the guy who punches people in the face is probably safer than the guy who sits back and lets his minions fight.
