I don't like level scaling much.
If it's off you can go doing easier quests you missed out before or kill easier opponents if you feel the need of a level up before advancing further.
I like the solution from AC:Odyssey (I think) where you could set the level scaling to a lower level, so quests did not fully scale but remained at a level -4 compared to you, so they were not fullay scaled but also not totally pointless.
