I think this is something that's very location based, in terms of priority. When I lived out in a country town accessed by twisty B-roads, I was all about performance gains, I didn't care for what stereo I had or the interior much at all. I had power gains as a top priority.
But since living on the inside of the M25, I've become more focused about creature comforts and how the car feels to drive everyday. I've since fitted coil over suspension based on what was more comfortable for everyday use, having all the suspension bushes replaced to give it that new car feel, fitted R32 bucket seat... You get the idea.
You need to decide whether you want to get to the corners quicker, or get round the corners quicker.
Or do both. t's much more fun.
