congrats Japanese brother
One potential benefit to heavy and sensitive steering is that it lets you know if steering has 'washed out' (the feeling of the steering lets you know when the front has lost grip)
When you drive really fast and the front end starts to push forward instead of turn, the tension in the steering wheel is gone. If you have a low steering ratio, it is harder to tell when this has happened.
The specification for this is called "steering ratio" and the M3 has one of the lowest or "fastest" steering ratios that you can buy.
A porsche GT3, most BMWs, most Mercs, many performance cars are 15-16:1. The E9x M3 and M5/M6 from this generation are 12.5:1. The new M3/M4 are 15+.

here's the best video I can find for steering ratio.
When you look at the suspension parts on various cars, the M3 and other performance cars have less rubber or soft parts that bend when you steer hard, which makes the steering feel stiffer. I'm not sure how proficient your technical English is, so I'm trying to explain this as simple as possible. Your post had very good English though, but it is hard when talking technical terminology.
Kajiura wrote which stimulates my propensity. (But the quality of AMG was great, it wasn't my preference)
'stimulates my propensity' could / might translate to ' excites me / makes me want it / makes me interested ' etc.
'but the quality of the AMG' could translate to ' even though the quality was good it was not my favorite car' or ' [despite / although] the quality being better, I did not like the AMG the most'.
