I like both. I'm not a solo diner so not sure what variables you are weighing. Food is comparable unless you want sushi, then CG wins. Service is hit or miss at both.
View is unquestionably better at CG. Almost no view at Citricos. You can eat at bar at either if that's of interest. Citricos is more relaxed, while CG is always a bit active. Fun, but more buzz.
Citricos, though, allows the opportunity to go early and catch some of the orchestra or pianist in the lobby before heading in to dinner. I happen to love that, and I like to do it with a cocktail from the always friendly Citricos bartenders.
I don't think you can make a wrong choice.
