I have had the pleasure of owning several Caymans. I had an 08 Cayman S, 2012 Cayman R, 2014 Cayman 2.7L, 2016 Cayman 2.7L, and now a 2019 Cayman 2.0L. I have seen improvement/refinement in each iteration. I will say that, overall, the 718 has represented the most significant change for me. I think the thing that impresses me the most is the smoothness/linearity of the acceleration (I know, that flies in the face of the dreaded 'turbo lag'). This was probably the most pleasant surprise. So, as GregW suggested, best to drive each and decide based on what floats your boat.
