I drove the Alfa in "D" ("Dynamic"), yes. The steering was excellent, but way lighter than I prefer. That's a preference issue and I don't count off for that, though. The upshifts were typical ZF8---Fantastic! However, downshifts especially after slowing were a "Let's talk first..." affair. You did not get immediate response, there. Further, acceleration from a stop took about 1/3 of a second to begin. Again, a "let's talk first" thing. I guess I could have got a JB4 and tuned that nonsense out of it, but really, why should I have to? The brakes were a bit odd, but that's normal for the car and something you adjust to. The vehicle was well weighted and tracked well through sweepers and tighter transitions, but I did not appreciate all of the body roll. In short, yes, it was very well weighted, but the responsiveness (or lack) in daily traffic really put me off. The RDX was more immediate with everything, the torque vectoring was legit tangible and neat, and felt more buttoned down even though it was weighted much worse and preferred on-throttle through corners instead of trail braking. You drove it different from the Stelvio, and objectively it was slower, yes, but it was so much more FUN! You also like Miata's, I see. I hate them. I hate how they drive. I acknowledge their technical prowess, but I'd never own one. I much prefer the BRZ/86. So this comes down to again, right car for the preferences.
I would also note that you did indeed dump your QV. That's worth noting, for whatever reason you chose to, you did, and that's a salient point.
