I would say Jiko. We've eaten at Citricos a couple times now and Jiko probably 20 times or more, and while Citricos is a good meal for the most part, it just doesn't have the "wow" factor that we get with Jiko. When I saw "wow," I'm referring to atmosphere of the restaurants, as well as creativity & flavors of the menu items. Everything I've ever tasted at Citricos has been a little -- well, a little bland.
Now, we've eaten twice at Jiko since Brian Piasecki has taken over, and I'm hoping things improve as he gets more settled and cozy. I have never been a fan of Le Cellier, and I was hopefully optimistic when he took over Jiko. But the portion sizes the entrees have been greatly reduced, and all the dishes we've ordered have been over-salted. The little details to the dishes that used to be there slowly seem to be fading, too. Like the edible flowers that used to be served with the filet have dwindled down to practically nothing. The two times we've eaten there since he's taken over in the kitchen, the bed of edible flowers and exotic microgreens that used to be is now just a typical salad with (I'm guessing) watercress & arugula. Same with the flatbreads; the microgreens used to be a real part of the flatbread, a topping, if you will. The last two flatbreads we've gotten have barely had any microgreens on them.
The wine lists at both Citricos and Jiko are wonderful. We've always thoroughly enjoyed all the wines we've ever ordered at both eateries.
So even with what I'm beginning to interpret as a bit of very recent homogenizing and cost-cutting of the menu at Jiko, I'd still recommend Jiko over Citricos.
What I'd recommend more than anything is that Disney bring back Anette Grecchi Gray!
