Galaxy Nexus to Pixel 6a (current) user. I did not have a pixel 1 or 2, but have had the rest. That Nexus 5x hung on for a while, as it should, being one of the best phones of all time, helping me skip right into pixel 3.
Side note: Nexus 7 was the greatest tablet of all time.
Out of any android, I preferred the nexus (now pixel) for it's simplicity. It's the way android was meant to be. Every other OEM is just someone copying the smart kids homework and making up random bullshit to call it their own.
RAM holds the apples you gave it until it is knocked out and drops them all and has no idea what an apple is when it wakes up.
Flash holds the apples you gave it and sets them down in the exact order you gave it to them, sleeps, and picks them back up again when it wakes up ready to hand them back.
Usually, the larger the drive, the less $ per GB. 16 and 18 TB drives for example would be where you would want to aim for if you're starting out fresh.
If you want to mix and match what you already have, unRaid is an option that does that well.
