It's so funny that the Pixel 3a feels so small after using the 6 for a few weeks. I would never have thought of my 3a that way.
I was a bit on the fence about the Pixel 6 size and while it has disadvantages, it makes me want to use the phone for more stuff. Even watching anime on the 3a was not very pleasant.
Anything less (such as the 4a I used to have) is difficult to use to me.
