PixelExperience is an AOSP based ROM, with Google apps included and all Pixel goodies (launcher, wallpapers, icons, fonts, bootanimation).
Since Google pushed Android 12 and its changes to AOSP, ROM developers have hit the ground running, and for selected hardware, you can now get a taste of the latest OS upgrade. Having access to the publicly available Android 12 source code was always going to accelerate any ROM development.
