This sounds crazy, but I am loving the OG Google Pixel XL in 2021.
I have bought a relatively cheap used OG Google Pixel XL 128gb and it still hangs in there really well. I use it as a secondary work phone and notice that I really enjoy picking it up. As my main driver I use a custom ROM Pixel experience Xiaomi Mi9 and sometimes I pick up the pixel xl over it just cuz it's so much lighter and easier to wield. The pictures taken are still fantastic and the speed it has is good enough.
I am going to receive a Pixel 6 soon and will continue to use the pixel xl as a work phone. Especially since XL gallery syncs with full original quality. I will auto transfer items from my 6 (as I do with my Mi9) to XL and work it that way! Never had an ecosystem quite like this and I'm loving it so far.
If anyone is looking for a cheap good way to have unlimited storage on Google cloud or a secondary reliable cheap smartphone. This is it.
