I am probably going to get a lot of flack for this comment.
I have owned 3 performers, 2 Green 07 models and an 02 Blue SS.
While I like them just like I like most kettles, for my preference, if I had one kettle to choose from them all give me a master-touch. I simply don't have the space for all the kettles, three legged grills work best for me due to being compact and portability.
