Don't let your competition hire away your top talent.
Right now its just ok. My friends S class has visibly mis-aligned buttons (a 200k car). My other friends electric S-class bean-thingy has squeaking doors (a 2 year old, 120k-when-new car) and feels surprisingly cheap to touch and drive. Sure, small sample and all of that but I don't think those are exceptions.
I only drove one Chinese car, and it was just a normal experience - what I'd expect from a volvo, bmw, or audi. Good UI on the infotainment, was below average annoying. No big difference vs. a merc. For sure not a qualitative difference in levels of refinement.
