I mean, yeah, its all relative.
As a backseat observer, I can tell you that at MSRP, the 3070TI isnt a great choice. At $100 more than the 3070, the extra performance isn't there. At $100 less than the 3080, you are leaving a lot of performance on the table.
Of course, the 3070TI is still a great card. It is certainly better than the 1080TI that I am running. And at a time where getting your hands on any 30XX card is very difficult, your only options are buy what you can find - in which case comparisons aren't exactly relevant - or you wait an undetermined amount of time.
For most people though, you don't need the biggest and the best card. Not to mention that these cards are often financially out of reach for a lot of people. There is a very good reason why the XX60 series cards are often the most popular, because for most people, they are just good enough, and they wont break the bank.
