I’m on my 6th e46 m3 and I have a b8 s4 daily driver and this is a fair comparison of the two. The m3 is very precise and very quick in an analogue way that keeps the driving experience pure. The s4 is a bit numb by comparison. Very nice place to be and very quick in a modern digital computer controlled way. The 2 cars are virtually identical in timed performance specs and they couldn’t be more opposite in how they go about it. For me the m3 is the car that makes me smile. the s4 is very dependable and easy to live with. And makes me relax
