Why are you even asking this again, read my post i've just answered you that exact question, YES somewhat worse bugs on earlier models, but MORE bugs that DOES NOT GET FIXED on later models. Reading and generating error logs is getting to be more of a massive chore and it did not use to be like this.
AGAIN, comparing how bad the bugs were on a debut piece of software and 10 years after is, to put it politely, not very telling at all.
Especially not when considering a product that has seen little advancement for years and has a budget more than 500 times larger than the debut model, literally!!!
There is every reason to wonder wtf is going on with Apple, but trying to gauge if IOS has less severe bugs now than 9 years ago and concluding that it does so that must mean Apple is doing great is just moronic.
