The “best” google phone has never been the best google phone. Their flagship tier has always been sub-par. Their budget tier on the other hand tends to be pretty good. The a series has traditionally offered one generation old tech and a great camera for a good price. There is no 8a, but the base 8 is already down to $550 so it seems to be taking that role. They do well in the mid-range.

If you want a top of the line flagship phone buy an iPhone. No one is competing with Apple right now on that front.

You definitely should not upgrade until the 40-series supers hit. They are rumored to start around January. If the rumors are true the 4070 Ti Super will have 16 GB of VRAM, a healthy performance boost, and pretty much make the 4080 irrelevant. And if you are happy with just a 4070 Ti the supers will force the prices down.
