As a past M3 owner I know what it's steering feels like and complete agree with the opinion of Quattrofun. The only odd thing that I have found from these reviews is that most prefer the 'comfort' setting on the dynamic steering, I think this is down to their limited time with the car because over time I have found that the 'auto' setup offers the best compromise between weighty 'dynamic' setting and the overly light 'comfort' setting, plus it offer enough feel to let you know when the tyres are struggling without making the steering feel busy on a bumpy road.
One thing I have to agree with you on is that things like steering feel is objective, what pleases one person won't necessarily please the next. The same is true for most things that require personal taste, including engine note among other things, at least with raw data you can understand this and appreciate what it means and it does help you narrow down your list of possible hopefuls to a small enough handful worthy of a proper test drive from which should help you decide which one suits you best.
Such a beautiful car. Can't wait to see if they do any changes to it with the A5/S5 being facelifted.
