Performance by a long way. Partly because on my previous car I got used to the speed as big numbers right in the middle and at work I'm used to scanning for speed as a displayed number, not on a traditional speedo... that may come into it.
I also just prefer the rev sweep rather than on the side. I've tried them all and elegant as a second.. I like playing around with the white arc on adaptive cruise to 'learn' where the car will start to pick up and want to adjust as you catch up on traffic. Second I'm done with that game it is straight onto Performance. Eco I don't bother with as I don't drive it an eco friendly manner!
