FWIW I was on Pixel 3a until last month; bought Pixel 6 in the meantime, but it was too big and heavy to carry around, so I only used it as a "tablet", only at home.

Just updated to Pixel 8 and it fits the hand very well (including Spigen Liquid Air cover), and doesn't feel too heavy. Have a few friends who got Pixel 8 last month on sale as well and they all confirm.
