I've tried both, and I liked them equally as much. I think Encore was a little more elegant, the service at Qua was a tad better but otherwise one isn't really any better than the other for me and Encore costs less. Qua has a couple more features than Encore, I found Encore to be less crowded. I personally would go with Encore from here on out since it costs less but if I were staying at Caesars I'd probably go with Qua out of convenience.

Thanks for the input.
