I took a quick gander at https://www.gadgetsnow.com/compare-mobile-phones/Google-Pixel-3-vs-OnePlus-6T but for me the reason I want a Google phone is they did keep the OS current for years on old models.
Google did roll out fixes for the Pixel but if you can swing the One, why not?
I was interested in the Google Pixel3 however just saw a review for the Oneplus 6T and now I'm torn. Was just wondering peoples' thoughts on which phone is better?
