The complaints weren't overblown at all and they weren't just about colour shift. There was the grain, image retention, black smear etc. It was the worst screen of any flagship phone in 2017. Any other LCD/AMOLED screen was substantially better in every respect, and yet Google charged a high end price for the 2XL with it's plastic feel, bad screen and myriad of QC issues is offensive. Pixel 3 has even more QC issues and bugs embarrassingly. Plus the slowdown has stained the Pixel brand and 'pure Google' experience which used to be a positive. Now they're just things you tolerate to get to use the camera. And even there competitors have caught up/surpassed Google.
Now with the Pixel 3a series, this actually kinda looks like Pixel phones that might be worth the price. A good camera, decent screen etc at a cheaper price. I don't see any reason to buy the 3/3XL - probably because they were really mid-ranged phones charged at full price, so now the 3a phones make much more sense for the price. The tradeoffs in hardware seem fair to hit that $400 US price. The ram is now reasonable for a mid-range phone. And if you're getting the same camera experience, I personally wouldn't spend more and 'upgrade' to the regular Pixel 3/3XL. Better off saving the money imo.
I'll keep an eye out on the Pixel 4a/4a XL. Might be decent value Pixels with hopefully the same cameras as the Pixel 4/4XL.
