I am not sure if it is better. But it is lighter since the one I got had most nothing pre installed, not even Google Drive, and let me uninstall some useless stuff. It do not even have a part that show how much memory is been used.
I have a Samsung tablet with 2GB of RAM only 650MB free, with Android 9. I will try install and check. So after I tell you what happen. I do even play Second Life in it sometimes.
... Oh It said it wasn't installed... But I have only 3,5GB of free HD in it. I will delete the PC copy I downloaded to try in joiplay.
