TI Petite Suite or MGM Celebrity Spa Suite?
As a property overall I prefer MGM but when it comes to rooms TI's have been renovated and are nicer at this time. MGM will be remodeling and that will change my opinion in the future I'm sure. I stayed in a TI Petite Suite this summer and loved it. I think the suites at MGM are in need of some remodeling so I wouldn't pay more to stay there if I were you unless you just prefer that end of the strip that much more.
