I think the Porsche GT3 RS vs. Mercedes-AMG GT R debate is a pretty cut and dry one. One is like going to the symphony, while other is going to a rock concert. Both have their places and can be highly entertaining, and neither is in any way not a totally fulfilling machine. Of course the RS is the symphony with its precision skills and nearly flawless execution of nearly everything you can throw at it. While the GT R is the rock concert with its thrashing handling, roaring sound, and wildness that will keep you up to the edge and maybe even over it if you aren’t careful. Which would I chose? Oh man.
