I have eaten at both several times and really like both - I personally feel CG is a little more sophisticated in it's menu, but found Narcooses food just as well prepared - I have had good service, and just fair service at both (one time when we were in the wine room at CG I had this spotlight beating down on me - it was really irritating, but the server said he could do nothing about it (no way to dim it). He did try to accomadate us eventually by moving our table, but it helped only minimally. On the plus side this room was a bit more quiet. I must say the one time I went to Flying Fish I had the best meal ever on-site at wdw, and hands down, the best server. It's just that the atmosphere at the other two are more romantic (though go late if you want a quieter meal.)
