I've eaten at both plcaes only once, so I don't pretend to know everything about them. Also, you're comparing regular and signature. I'll just say that we (family and I) liked, didn't love, The Wave and had a horrible night at Citricos (glacial service, undercooked filet and overcooked fish). That said, I alwas opt for signature over regular if I can afford it, and I'm always prepared to give a restaurant a second chance.
Going to Citricos feels more like really going someplace. Going to the Wave feels like hitting any hotel's retaurant/bar (especially since it's right next to the main desk). But your wallet's gonna feel it more, for sure.
