Some good thoughts here. I used to say nice hand every time because I wanted people to think they played well, but people can take that in a lot of different ways, and I don't want people to think I'm being sarcastic. Right now I don't say anything at all. I like to try to give off the impression that I'm tilting if possible, but it's better to think about how you could have played the hand better and about the other hands you're in then to try to think of something clever to say imo.
