Why do you say "with much worse support"? That's not the case anymore, at least for Pixels.
The pixel 6a will get 3 years of updates and 5 years of security updates. On a phone that was released 12 months ago.
So it hasn’t been tested yet. Plenty of time for google to renege on that.
The Pixel 6a is at least a cheaper phone. But the Pixel 7 are flagship prices for the same support.
iPhones have been getting this level of updates since almost day one. The last iPhone I ran into the ground was a 6 and that had 5 years of OS updates. iOS 8 through 12.
My current XR has been getting updates for almost 5 years and will get iOS 17. So at least 6 years of updates?
I installed some ROM and kept it alive (not by far as secure as using an iPhone, of course).
Google and Samsung appear to be on the same page; I think the front runners in the Android world are a lot better than some would like to give them credit for.
