Being a lifelong motorhead this is a tempting choice. But also being a motorcycle enthusiast I need the open air experience. Hence, any variant of the Boxster will come out tops for me. Open air motoring puts you into the environment and the experience as opposed to being insulated from it. Being enclosed in a coupe or sedan reduces driving to a bit like watching TV. The passing environment framed by the glass windshield flickering passed us while we sit watching, insulated from air currents, sun, scents, sounds and vistas. IMHO
I must admit (despite Robert Pirsig philosophosizing), I have never had the luck to drive a Carrera coupe. Perhaps the experience is so awesome, I'd become a convert.
