S6. It rides better, looks better, has vastly superior interior, better quality materials, more rare, more prestige, etc. Seems like you're blowing through money like crazy. You might as well look the part. Also, the S6 is just a tune away from 500+HP. Zero - 60 in under 4 seconds, stock. Tuned will be mid to low 3s. Plus, hot V twin turbos are all the rage right now.
