To explain a little on ram plus.
Say you have 5 apps open.
Then you open fortnite, fortnite will use loads of ram, so your phone will stop those 5 apps to make room for your giant app of fortnite.
With ram plus, those 5 apps should be sent to your storage instead. So when you go to open them, it takes a second but they resume where they left off. Without it, those apps would have to restart.
It's a system called swap in linux or a page file in windows. It also prevents running out of ram and your device crashing, though I think it's always on a tiny bit to prevent that regardless of your settings.
On paper more is better. In reality, try it and see.
