Vijay-
I have both a 2022 EQS 580 SUV and a 2020 Tesla S. I could go on here for hours comparing the two, but I have to agree that Tesla's frequent updates are reassuring in theory, but typically, I experience no difference in the car's performance or in the driver's experience when there is an update. So, at Tesla, IMO, what they're doing much of the time serves their internal purposes - fixing things, bragging rights, marketing, legal, those kinds of things. I can't remember an update that perceptibly improved the car.
Meanwhile, my EQS had some problems early on, was in the shop for several days, with no solutions other than the usual software reloads, etc. I was upset and waiting for the next problem to occur when I would be within my rights to file a lemon law complaint. Since then, the car has been getting consistently better. Very few random error messages, nothing of great inconvenience let alone requiring a shop visit. I don't know if this is due to updates I am not aware of, or the car "learing", which it does in some ways, or what, exactly.
But at this point, I truly look forward to driving the EQS, thoroughly enjoy it, and really tend to not want to drive the Tesla at all. For more than one reason. The quiet, the steering assist (flawed but still better than Tesla's), the build, performance (I don't race anymore... left that on the track years ago), utility, comfort are significantly better imo than Tesla.
Strangely, my partner was away for 7 weeks. I have to say she does not like the car, principally because it had so many issues early on, and because it seems to have an issue frequently when she is a passenger in it, and when that happens and she is in the car, she complains about the car. The car had no issues, none, the entire time she was away. Driving to the airport to pick her up, I was honestly thinking of telling her how brilliant the car had been the past month or so. So, I picked her up at the airport and things went wrong the instant she got in the car - the heads-up display disappeared, navigation screen changed, a layer I'd never seen before popped up on the center display, an indicator of a car seat or something in the passenger seat where she was sitting, few things like that, strange glitches, as if the car was aware of who was riding in it.
Drove home without the heads-up, which, once you get used to it, feels really wierd to be without. Thought I'd leave it overnight and check in the morning. This morning, all is corrected and good, as if the car repaired or reset itself over night. This is the second time I've had that experience with it.
So that's what I can say about that. In general, I think the car is brilliant - superior to the Tesla.
