Spent some time with one a dealership recently but didn't get to drive it. Have driven the S5 though...it is fast and competent but steering feel [as typical of Audi] left a lot to be desired. I can't imagine the RS5 being much different.
I felt the RS5 Sportback is a good looking car but is also very teutonic, especially the interior. Whole car just lacked personality in my opinion. This is something subjective that can't be quantified obviously, but I much prefer the ///M3 and C63 Merc.
I'll admit, however, I tend to be biased against Audi. I don't see myself ever getting one as my personal car...maybe a Q7 when I have a family or something. But BMW ///M division and Porsche are the cars I lust after.
